Any detail that is in permanent operation is able to wear out over time. The brake system is no exception. And since good brakes are one of the main conditions of the safe driving, to their diagnosis and timely replacement should be considered with all the responsibility. About this further in the article.

Causes of brake disc wear and pads

Together with brake discs, as a rule, pay attention to the state of the brake pads, the replacement of which is desirable to produce together. The reasons for replacement exists a thousand and one, however, a special feature indicating the need for replacement is the beating (or knock) of the brake pedal during the braking process.

The pedal beating is peculiar shocks that are well felt in the process of sharp braking at high speed. If you think that the discs will serve a little more, or wait that the car will just get up, make a huge mistake. Similar expectations are able to bring you directly to intensive care.

If the brake pedal is shawl, there may be several reasons for breakage:

1. The brake disc is fed up - the most common malfunction. This happens with it as a result of the temperature difference - sharp heating and cooling when braking, natural wear. This unit should be replaced, and necessarily together with another, even when the second is still in good condition.
   
2. Can fail the front blocks - they also do not reanimate them.
3. Most often, the drum brakes are behind (because the drive front and not quite reasonfully spend on the discs behind the disc), they break.

It is important to know that all manufacturers producing brake discs for VAZ 2114 are not able to guarantee their certain expiration date. A breakdown of an important element of the brake mechanism - in fact, the situation is unexpected. This is due to the fact that their health directly affects the quality of components and quality of roads. Therefore, the best thing that can make a car owner is to systematically look at their condition.

So, it is possible to distinguish three reasons that affect the velocity of brake discs and pads:

1. Production material.
2. The correctness of the operation of the brake system.
3. Driving style.

Wear brake discs and pads, how to check wear with your own hands (step-by-step instruction)

1. To check the wear of brake discs and pads, VAZ 2114 should be put on the parking brake and install special stops (shoes) under the rear wheels.
2. Then weakening the nut, which fix the wheels, and raise the vehicle to the jack.
3. Next, we unscrew and completely dismantle the wheels, and the brake system elements purify from dirt.
4. Now with the help of the calipers perform measurements. If they showed that brake pads and discs were worn to a critical minimum, they must urgently replace.

Also, the replacement of nodes is required if the visual diagnostics showed the presence of any mechanical damage - curvature, cracks, potholes, chips or backlash in connections.

Permissible thickness of the discs, thickness of lining on the pads, the diameter of the rear drum brake

The minimum permissible thickness of the brake disc - 10.8 millimeters.

The thickness of the linings on the block is 1.5 millimeters.

Drum rear brake diameter - 201.5 millimeters.

In what cases urgently requires replacement of braking assembly

1. Beats in the brake pedal.
2. Surrive in braking.
3. The presence of a gap between the base and lining.
4. The pads of the pads were grilled.
5. Invalid thickness value.

Tools, fixtures, consumables

1. Rubber hammer.
2. Balloon key.
3. Keys on "13", "17" and "8".
4. Screwdriver.
5. Jack.

How to replace the brake disc and pads (step-by-step instruction)

Replace the discs in such a sequence:

1. We put the car on a flat surface and install anti-tart stops under the wheels.
   
2. If the wheels have not been filmed for a long time, process all threaded connections using WD-40 and wait 10 minutes, which will significantly facilitate the dismounting process.
3. Next, using a balloon key, we climb the nut with a dead point, fixing the wheel. Since the vehicle can hardly swam, it must be done before raising the car on the jack.
4. Now raise the car on the jack.
5. We twist all locking nuts with a balloon key, after which we remove the wheel.
6. We dismantle the block, for which you unscrew the locking caliper with the help of the key to "17". Pre-key to "13" dismantle the brake hose fastener and drain the flowing fluid in the prepared container.
   
7. Remove the brake cylinder, which is fixed with two bolts, they are twisted with the key to "13".
8. Next, using the key to "8" unscrew the two guide pins, which are fixed in the brake disc. The latter does not have to turn.
9. Now the rubber hammer is tapping the back side of the disk and remove it.
10. Installation of the new element is performed in the reverse order. Do not forget to lubricate the connection location with high temperature lubrication before installing.

The replacement of the pad is made as follows:

1. After dismantling the wheel and cleaning elements from dirt, we take out the brake fluid supply hose from the bracket.
2. The key to "17" unscrew the upper fixing bolt of the caliper.
3. Next, weaken (you do not need to completely unscrew) the lower mounting bolt of the caliper.
4. The brake, which closes the brake pads, move up.
5. We remove the wear blocks and install new ones.
6. We spin the caliper back, fasten into the bracket of the fluid supply hose and install the wheel.

Tips Prof.

As you see, replacing the pads and disks - the procedure is quite time-consuming, but not complicated. If you have never done this before and doubt your abilities, that is, it makes sense to resort to the help of car service workers, where for the appropriate fee you will do everything quickly and efficiently.
