Checking the condition, removing and installing the brake disc of the Jeep Grand Cherokee


Replacing brake discs on a VAZ 2109

Brake discs provide braking to the front wheels when the vehicle is moving. The effectiveness of braking, and, consequently, safety on the road depends on their condition. Brake discs on a VAZ 2109 are replaced in the following cases:

  • The thickness has reached the maximum permissible minimum value - 10.8 mm. At the same time, the thickness must be controlled in two places. If the wear is uneven, then replacement is carried out in any case.
  • The disc has deep scratches or chips.

Such noticeable defects on the brake disc occur as a result of using low-quality brake pads or careless driving on uneven road surfaces.

Using such a brake disc will inevitably lead to its breakdown and sudden braking at speed, or, at best, to a deterioration in braking properties.

Small scratches on the brake disc can be removed using special equipment. However, not every driver can afford such devices. In this case, the brake disc must be replaced.

Procedure.

  1. Place the car on a completely flat surface and install wheel chocks under the rear wheels on the front and rear sides.
  2. Engage first gear and prevent any movement of the vehicle in the horizontal plane.
  3. Loosen the wheel bolts on the side where you plan to replace the brake disc and jack up the car.
  4. Completely unscrew the wheel bolts and remove the wheel. Mount your car on special supports to increase safety.
  5. Now unscrew the two bolts that secure the caliper to the steering knuckle and remove the brake caliper. To make the task easier, rock the caliper back and forth to loosen the pads. Attention! When dismantling the caliper, do not unscrew the brake hoses, as this can cause a very sharp leak of brake fluid.

  6. As soon as you remove the caliper, hang it with a wire on any suspension element so that it does not interfere with the work. This will also prevent possible damage to the brake hose.
  7. Using a dry cloth, wipe the brake disc to remove dirt and other debris.
  8. Use a lubricant such as WD-40 to treat the joint between the brake disc and hub, as well as the guides. Wait approximately 5 minutes and proceed to remove the brake disc.

  9. Unscrew the 2 guides from the brake disc and try to remove it by hand. If this fails, then take a rubber hammer and knock it off the hub with gentle blows along the entire circumference of the disk. Attention! Be careful not to hit too hard, as the disc may break and accidentally injure you from the fragments!

  10. Install the new brake disc, insert the guides and tighten them. They should be tightened evenly and equally so as not to spoil the threads and not to disrupt the uniform wear of the disk in the future.
  11. Reinstall the caliper, replace the brake pads if possible and necessary, and screw the caliper to the steering knuckle.
  12. Install the wheel and tighten the wheel bolts.

  13. Remove the special supports and lower the vehicle.
  14. Don't forget to tighten the wheel bolts completely! Many novice drivers often forget this significant detail and get into an accident. Be extremely careful!


That's all! As you understand, replacing brake discs on a VAZ 2109 does not require special knowledge and skills. The most important thing is a minimum of knowledge and the availability of the necessary set of tools. Good luck on the roads!

How to remove a brake disc

In order to replace a failed TD, you need to perform a series of actions sequentially.

  1. Press out the piston of the brake working cylinder.
  2. Disconnect the caliper. To do this, two mounting bolts are unscrewed from the inside of the hub.
  3. Without disconnecting the brake hoses, move the caliper, thereby freeing the disc. Release the brake pads and secure them with a clamp.
  1. Secure the caliper using the prepared wire.
  1. On some car models, the caliper frame interferes with disc removal. In these cases, you need to unscrew the frame fastening and remove it.
  2. Before removing the TD from the hub, you need to unscrew the stuck fastening bolt, having previously lubricated the mounting location with WD fluid or brake fluid, if it is not available. There may be one or two such bolts securing the disc to the hub. It depends on the car model.
  3. Once the mounting bolts have been removed, you can begin to remove the TD. Often, it is stuck to the surface of the hub. To facilitate its dismantling, you need to lightly tap it with a hammer to separate it from the wall of the adjacent part.

Replacing the front brake disc of a VAZ 2109 on your own

Front brake disc

If braking noticeably worsens while driving, it is recommended that you conduct a detailed inspection of the entire braking system. Knocking noise in the front suspension can also tell a lot about the condition of the car. This type of problem can be caused by worn brake discs. As a rule, the degree of wear is checked only by visual assessment. Replacing the front brake disc of a VAZ 2109 is recommended when significant wear is observed. It is noteworthy that replacing the front brake disc on a VAZ 2109 can be easily done on your own. The presence of cracks and damage may also be the cause. Changing the front braking mechanism is not so difficult, so if you have competent instructions, the work will be completed successfully.

Replacing the front brake discs of a VAZ 2109

The thickness of the non-vented disc should be approximately 10.8 mm, while the thickness of the vented part should be a minimum of 17.8 mm. Change brake pads and discs if the indicators are less than normal. It must be taken into account that the axial runout of the surface should be less than 0.15 mm.

Note! If there are scuffs and deep scratches on the discs, braking efficiency will be significantly reduced due to greater wear of the pads. In this case, an urgent replacement of the rear discs or a change in the front braking mechanisms will be required.

Now you can get qualified assistance in grinding discs at a service station. Experts must take into account acceptable standards. The groove is made to the same depth on both sides.

Signs of brake disc wear

Every car owner wants to know when to replace parts of his vehicle. However, car manufacturers cannot give recommendations on replacement periods, since wear depends on:

  • Driving style. If you like to drive recklessly on the road, then the wear of all parts and components of the vehicle will be quite fast.
  • Quality of roads. On bumpy roads, the brake system wears out faster.
  • Car brands and models. Manufacturers usually do not indicate the service life of brake discs. However, auto parts are selected based on the general technical characteristics of the make and model of the car.

Based on this, the car owner himself must determine when to replace the discs. This can be determined by the degree of wear of the car part, as well as by certain signs of the car’s behavior on the road. Diagnostics of serviceability and subsequent replacement will be required if:

  • Brake fluid is leaking. This happens because worn cylinders and discs move out, jamming the caliper, which causes a leak.
  • The pad heats up quickly. Often the disc becomes red hot. Moreover, if at the moment of acceleration the car hits a puddle, the disk will crack from sudden cooling.
  • Controllability has decreased. The steering wheel begins to “jump” and pull to the side. This indicates damage to the front discs.
  • The brake pedal has become too soft and the braking distance is tortuous. This indicates wear on the rear discs.
  • An uncharacteristic sound appeared when braking. “Squealing” of the brakes indicates wear on the rear suspension discs.
  • You have discovered mechanical damage or noticed obvious wear on the discs.
  • You've been in an accident and your brake discs have been warped.

To replace front brake discs quickly and correctly, you need to be able to distinguish between the types of automotive components in question. Thus, they distinguish:

  • collapsible disks;
  • elements with grooves and perforations;
  • disks with special gas outlets;
  • ventilated elements.

The braking system is an important component of the car.

Replacing the front brake discs of a VAZ 2110

The car is considered one of the most dangerous inventions that man has invented. To make the travel of a vehicle driver safe, developers had to create many inventions. One of them is brakes (see Repairing brakes at home). Every vehicle has a braking system. To avoid any troubles on the roadway, before leaving, you should take care of the brake system. It must be constantly maintained in working order. In most cases, repairs to brake discs and pads should be left to professionals. But if you take on repairs yourself, you should learn a few basic rules.

Note: Brake discs must be replaced on both sides at the same time. Each individual replacement of equipment requires the implementation of clear established rules. If new disks were damaged during installation due to the negligence of the installer, sellers will not provide warranty service or replace the product.

When is it time to replace the front brake discs?

VAZ 2109 front brake discs

The front braking mechanisms on the VAZ 2109 are replaced in case of mechanical damage or when the working part of the disc wears out (thickness is less than the norm of 10.8 mm).

Note! Further use of a worn disc or element with cracks is strictly prohibited.

If there are minor scratches or abrasions on the functional surface, they can be removed by grinding the disc using specialized equipment in a workshop. If this is not possible, or the damage is so significant, you cannot do without replacing the part.

Replacing brake discs on almost all cars will be technologically the same. Now, after dismantling the wheels, you can begin dismantling the old disks.

First, press out the working cylinder bushing

, after which we remove the disk itself. To avoid the need to change the bearing, we get rid of the dirt and deposits that are on the caliper and hub. You need to ask someone to help hold the steering wheel and press the brake pedal all the way, and at this time you will need to unscrew the mounting bolts that hold the brake disc to the hub.

Next, the brake caliper and pads are dismantled. Then you need to remove the clamping element. After which the hub is fixed and the brake disc is dismantled. The process of installing new brake pads and the disc itself should be carried out in reverse order.

Naturally, having your car repaired at a service station is always good, but not when you need to save money. Today there are detailed instructions, photo reports and videos with a detailed description of the actions, so every car owner can change brake system discs. To perform the work, you need to acquire a standard set of tools and detailed instructions:

  • To begin with, you need to put the car in first gear or turn on the handbrake of the VAZ. Next, the wheel bolts are loosened.
  • The car is raised and the wheels are removed.
  • In the brake mechanism, from the inside, you need to unscrew the mounting bolts of the guide pads towards the steering knuckle.
  • The steering knuckle is dismantled, after which I hang it on a wire to the rack. You need to make sure that the hose does not get twisted or stretched too much.
  • The working surface of the disk is cleaned of dust, dirt, as well as wheel pins. If necessary, the surface of the disk, joints and small elements can be treated with a special liquid, for example, WD-40. Thus, traces of metal corrosion are eliminated.
  • Using a spanner, the wheel pins are unscrewed.
  • The brake disc is knocked off the hub by hitting it with a hammer from the inside through a spacer made of wood.
  • The part is replaced and the steps are performed in reverse order.

Since repairing or replacing parts of a VAZ 2109 car at a service station is expensive, you have to perform such actions yourself. Now, with the help of videos and photos, replacing the front disc with your own hands is as easy as shelling pears. For effective and high-quality work, the instructions must be correct and correspond to a specific type of car, since the procedure may differ. Today, the price of specialist services is not encouraging, so it is advisable to start studying your car yourself.

Replacing a brake disc on a VAZ 2108, VAZ 2109, VAZ 21099

Welcome! Brake disc - it is made in the shape of a circle, when braking, the brake disc heats up from 350-750 degrees Celsius, maybe more if the car is constantly braking and all this happens in extreme heat and on strong brake pads, but still, over time, the disc wears out just like any other part and there is a need to change it, this must be done, otherwise the car’s brakes will get worse and worse every day.

Note! To replace the disc, you need to stock up on: Be sure to have a set of wrenches, some kind of lubricant like WD-40 or itself, as well as a metal ruler or something else like it, because you won’t be able to determine the thickness of the old brake disc by eye , and the disk needs to be replaced only if its thickness has become less than 10.8 mm. In addition to these devices, you also need to take a hammer (Preferably rubber) and a needle file (The needle file is taken if your disk turns out to be normal, and you will install it again on its place, but more on that later)!

Summary:

Where is the brake disc located? On our cars there are only two discs, both of them are located in the front part of the car, while drum brakes are installed at the rear; many car owners are confused by the fact that disc brakes are not installed on the rear part of the car; in fact, the car would actually stop faster, but replacing the discs would be a pain. more expensive, so the engineers working at VAZ decided not to use discs on the rear wheels and leave them only on the front wheels; for a more detailed location of the brake discs, see the photo below, which shows only one disc and it is indicated by an arrow:

When should you replace a brake disc? Firstly, when something happens to the disk and thereby it becomes unusable, the first thing you will begin to feel is that the car will stop worse, and secondly, there may be a noticeable beat when braking in the front part (Usually in this case it beats the brake disc is too worn), and the disc needs to be changed if various kinds of defects begin to appear on it, for example, cracks, deep chips, etc., by the way, some small defects can be removed in a car repair shop, now some car repair shops are engaged in sharpening the disc in this In this case, the excess (Defective) layer of metal on the brake disc is erased and instead of the defective layer, a new one remains and the disc is subject to further use (This procedure can only be carried out on a thick disc, if you want to find out why, read the “Note!” section below)

Note! Under no circumstances should you operate a car if the thickness of the brake disc has become less than 10.8 mm, you are only allowed to go to a car repair shop or garage and change the disc to a new one, because when the thickness of the disc becomes small, it becomes much more susceptible to the fact that on it the body will soon begin to crack, etc., in connection with this, the disk may simply not withstand the load and thereby burst, thereby the brakes on the wheel where you had the disk will completely disappear.

Replacing rear brake pads Nissan Qashqai

Replacing the rear brake pads on a Nissan Qashqai is done in approximately the same way as on the front axle. We carry out the work in the following order:

  • loosen the wheel bolts, jack up the car;
  • remove the wheel, unscrew the two bolts securing the rear caliper;

  • move the brake cylinder to the side, remove the brake pads from the bracket;
  • Before installing the new parts in place, we press the cylinder into the caliper; you should press it carefully so as not to damage it;
  • we fix the new pads in their places;

  • We install the caliper and wheel in place, and remove the car from the jack.

The same as when replacing the front fuel pumps, after perfect work:

  • start the engine;
  • press the brake pedal several times.

The pedal may fail on the first stroke, but then it will press as it should with normal brakes.

How to replace a brake disc on a VAZ 2108-VAZ 21099?

Removal: 1) To replace the disk, you will first need to remove the wheel from the car and place either wheel chocks or bricks under the rear wheels, or simply put the car on the handbrake so that it does not roll away anywhere. (For information on how to remove a wheel, see the article entitled: “Replacing wheels on a car”)

Note! When the wheel is removed, use a ruler to check the thickness of the disk; if it is below 10.8 mm, then the disk needs to be replaced, but if it is not much higher, for example, 12.0 mm, then in this case it is up to you to change or not change the disk you, but in such a situation it won’t take a very long time to reach the critical point! (Be sure to check the thickness of the disk in at least three places)

2) Now look under the caliper, at the back you will see (Indicated by arrows) two bolts that will attach it to the steering knuckle, so you will need to completely unscrew these bolts and thereby remove the brake caliper from the car, without removing it you can remove it yourself disk from the car.

Note! When the bolts that hold the caliper are unscrewed and the caliper itself is removed, the first thing you will see is that some kind of hose is connected to the caliper and thus you will not be able to completely remove the caliper, so you don’t need to unscrew this hose and completely remove the brake caliper from the car, you just find a rag or some kind of wire in your garage or car and use it to hook the caliper behind the telescopic strut spring, as shown in the small picture above!

3) After this operation, you will need to take WD-40 lubricant or something similar and apply it to the guide pins (Indicated by red arrows), and to the part where the disc itself connects to the hub (The place where the brake disc connects with hub, indicated by four blue arrows).

Note! This lubricant is applied only to unscrew the guide pins and it was much easier to remove the disc itself from the hub, because from time to time rust forms in all places in the car, especially what starts to rust first is what is below and has at least some kind of contact with road dirt, and what has contact (Especially in winter) with road dirt? Of course, this is the bottom of the car and the brake system, so you need to lubricate all these places with lubrication, which are indicated by arrows in the photo above!

4) So, when you lubricate the guide pins with grease, pick up a wrench or an extension with a socket head and completely unscrew both of these pins and then put them aside in some kind of box so that they don’t get lost, or put them in the car.

5) And at the end of the operation, grab the disc with both hands and try to pull it from the car, but essentially this method is pointless, so if you have a rubber hammer or something similar (In principle, a regular hammer will do, only for them you need to hit it more carefully without breaking the disc itself), take it in your hands and twist the brake disc in a circle, hit the hammer on the back side of the disc in different places so that it first comes off the hub a little in one part, then a little in another and so on, this is how you remove the disc from the car.

Note! There is no need to hammer with all your might just one place on the discs, it will be pointless, so be sure to twist it!

Installation: Install the new disk in its place in the reverse order of removal.

Note! If you reinstall the old disk, pay attention to the fact that a bead has formed on its edges; you will need to remove this bead with a file and thereby make the disk even!

How to change brake discs on a VAZ 21099 yourself

If you notice that the stopping distance of your car deviates from the norm, this means that the brake system is worn out and requires thorough attention. All thoughts should be focused on solving the question of how to change brake discs on a VAZ 21099 and check the pads. Let us remember that the brake disc is a metal structure made in the shape of a circle and installed on the front axle. The disc actively takes part in the braking process and tends to wear out after a certain period of time. If we talk specifically about VAZs, then most often they have only two brake discs on the front axle, but the rear of the car has drum brakes, other manipulations are carried out with them, the procedure is not the same as changing brake discs on a VAZ 21099. This factory equipment is well thought out initially, and in principle functions reliably.

Where to buy brake discs

In order for the brake system to last as long as possible, it is necessary to purchase only high-quality certified parts. The modern car market is replete with a huge number of spare parts, including many low-quality analogues. Their price is several times lower, which attracts car enthusiasts. Such a temptation will soon lead to even greater costs. Therefore, to make driving your favorite car comfortable and safe, you should purchase spare parts only from trusted manufacturers. Buying brake discs in the Dvizhkom online store means guaranteeing reliable and durable operation of the brakes. We work only with well-known domestic companies, so our products meet all quality and safety standards.

When is a brake disc considered worn out?

Imagine the conditions under which a brake disc has to function. The part interacts with the brake pads and caliper; during movement, the disc heats up to 350 degrees Celsius. And if it is the summer period, driving in traffic jams, then the load on the brake system increases, as a result, rapid wear and tear and the urgency of the task of how to change brake discs on a VAZ 21099, the choice of a specialist to whom you will have to contact.

Brake disc VAZ 21099

After studying the technical documents, it becomes clear that brake discs with maximum operation can withstand 50,000 kilometers, and then you need to think about how to change the brake discs on a VAZ 21099 and check the entire system. Experienced drivers who have mastered the skill of smooth braking are lucky; they never use emergency braking, because their discs will last until the car’s mileage is 100,000 kilometers.

Measuring brake disc thickness

The moment of alarm for a part can be determined by visual inspection and measurements of the disk. If it turns out that its thickness is approaching 10 mm, then this parameter is already critical and requires action to be taken immediately, otherwise the task of how to change brake discs on a VAZ 21099 will have a difficult solution.

How to monitor their condition?

If the thickness of the brake disc is about 11-12 mm, there are various kinds of abrasions and grooves on its surface that reduce the quality of braking, then you should think about replacing it. In this case, the brake pads begin to wear out much faster, and extraneous noise appears when the brake system operates.

To determine the degree of wear of the brake discs, you need to use a caliper, and check the data obtained with the table of permissible values ​​for brake discs and pads, which can be found in the owner's manual for your car.

The quality of the vehicle's braking system directly depends on the technical condition of the brake discs and pads, which must be periodically checked for integrity. Also, the condition of the brake system elements will tell the car owner when to change the brake discs and pads.

To replace brake discs with your own hands, you will need simple tools.

Having made it a priority to solve the problem of how to change brake discs on a VAZ 21099, at the same time think about when it is more profitable to take the time for repairs and go to the garage to resuscitate the brake system of a personal car. You will need:

    A standard set of reliable wrenches for removing the brake disc. They provide a reliable grip on the fasteners; with their help you can grab nuts of different sizes and unscrew them.

A set of wrenches WD-40 lubricant is purchased, which helps in working with soured fasteners when the process of how to change brake discs on a VAZ 21099 is started, so work is carried out with tightly tightened nuts and bolts.

WD-40 lubricant A metal ruler for taking measurements, because you shouldn’t judge the condition of the disc by eye. Let us remind you that the critical thickness of the part is 10 mm.

Metal ruler Rubber hammer for dismantling the disk and placing it in place. Iron can also be used, but it can create a precedent, causing unwanted damage to the metal part.

Rubber hammer You will need both 7 and 19 mm socket heads. It will not be superfluous to prepare a wrench and a ratchet to solve the issue of how to change brake discs on a VAZ 21099.

Grooving brake discs - what is it?

Grooving is the process of processing disk surfaces in order to eliminate their deformation. With this type of grinding, the unevenness is eliminated and the disc becomes as good as new. Almost all car services do the work.

Repairing discs by turning is possible if there are no cracks on them and provided that their thickness upon completion of the work does not exceed the maximum dimensions. The limits are individual for each model.

There are 2 common cutting methods:

  • on a conventional lathe (with removal);
  • without removing the disc on the machine.

We are considering one of the options for changing brake discs on a VAZ 21099

  1. The machine is securely fixed at the repair site. For this purpose, wheel chocks, bricks, and removed tires are used, which are installed under the rear wheels. You can also use a hand brake so that nothing gets in the way of deciding how to change the brake discs of a VAZ 2107.

Important! Take a ruler and estimate the thickness of the disk; perhaps repairs are not yet needed. Measurements are taken in several places. The condition of the metal is assessed and the presence of chips and scratches on the disc is excluded.

    We remove the front wheel, where the procedure will take place to decide how to change the brake discs of a VAZ 2107. We recommend gradually loosening the bolts on the wheel, and then completely removing the tire by jacking it up.

We remove the front wheels. The brake pads and also the caliper are removed. It is worth working with fastenings carefully. Carefully inspect the brake hose, if possible, move it to the side and secure it, and then decide how to replace the brake discs of the VAZ 2107

Removing the brake pads Apply WD-40 to the fasteners that connect the disc and the hub, they will then yield more easily to the force of the tools used. It’s better when the understanding of how to replace brake discs on a VAZ 2107 manifests itself smoothly in practice.

Lubricating the fasteners The disc can usually be removed without much effort, but if difficulties arise, use a hammer and remove it from its seat with confident and periodic blows. And the rhythm is as follows: several blows and spinning the disk so that it can be dismantled.

Removing the brake disc

Important! You have a removed disk in your hands. Assess its condition. Thickness is normal! Are there any deformations? Then you can return the product to its place, but under one condition! Which one? Pay attention to the edge of the disk; an unwanted bead has formed there during operation. You can really remove it - you can just grind it off with a file.

  1. The disk has been dismantled, but do not forget about the edging, which is located along the perimeter of the working part of the disk. The protector should be removed to free the seat from unnecessary parts.
  2. One of the last stages of solving the question of how to change brake discs on a VAZ 2107 involves returning the disc to its place. If you suddenly need to clean the repair area, you can perform all the necessary procedures and eliminate dirt and old grease.
