The brake system should always be kept in good condition because it is closely related to the safety of the ride. As you know, with brakes jokes are dangerous, so you need to change the brake pads in a timely manner, regularly check the performance of the manual brake, follow the condition of the drums and disks. From how qualitatively maintenance is observed and the timely replacement of elements is carried out, not only the performance of the vehicle, and the safety of its driver and passengers depends. About this further in the article.

Brake system VAZ 2114, how it is arranged, how it works

The brake system on the VAZ 2114 car includes two main parts:

1. The drive is a system that is intended to transmit effort from the squeezed brake pedal to the wheeled mechanisms.
2. Wheel mechanisms - directly affect the parts rotting along with the wheel and slow down its turns.

On VAZ 2114, a two-circuit system of brakes with hydraulic drive is mounted. What does it mean? And the fact that the effort that appears from pressing the brake pedal creates the fluid pressure in the entire system (hydraulics). This pressure makes the wheeled cylinders work. The word "dual intention" suggests that the effort from the pedal is transmitted through two line-independent lines (contours) on the wheels of the wheels. Data contours have a diagonal location: the right rear wheel works along with the left front, left back - with the right front wheel. In the conditions of failure of one of the contours, this decision makes it possible to maintain the stability of the vehicle during braking, especially on the rotation and slippery road.

The main condition for the performance of the system is its tightness. Therefore, it is very dangerous to operate transport with leakage of fluid. No less dangerous air in the brake system. During compression, the air has been repeatedly reduced in the amount, in contrast to the fluid, which in comprehension actually does not change the volume. During the braking of the vehicle with a leakage system, the brake pedal can "fail", as a result of which the brakes will not work.

Scheme of the brake system VAZ 2114

The scheme of the brake system on the VAZ 2114 has a classic assembly: the main brake cylinder (1), the metal pipes of the first circuit (2), the flexible hose of the front mechanism (3), the tank for the liquid (4), the vacuum brake amplifier (5), the metal nozzles of the second Contour (6), rear wheels (7) cylinders (7), brake pressure regulator drive (8), flexible rear mechanism hose (9), pressure regulator (10), pressure regulator bracket (11), pedal (12).

Rear pads VAZ 2114, 2108, 2109, 2113, 2115, periodicity of replacement and from which depends

Unlike disks and disk pads, drums and drum pads have a longer service life. However, sooner or later, still has to be replaced. There is no strict framework, after a distance or time period should be changed the rear brake pads, on the VAZ 2114, as a rule, the replacement is produced every 70,000 mileage kilometers. However, the frequency is different, to which different factors affect:

1. The condition of the drums.
2. Car operating conditions.
3. Bus owner driving style.
4. Quality of pads and their friction linings.

Emergency braking of the car, how it affects the wear of the pads

Continuous emergency braking entails premature wear of the friction layer of the pads, the brake system components in rainy wet weather are much faster. If the inner surface of the brake drum on the VAZ is worn unevenly, the pads are also unevenly wearing.

Rear pads VAZ 2114, what to choose, the best firms manufacturers

To date, rear brake pads for VAZ 2114 make different companies, therefore, product quality can also be different. Spare parts of the original production AvtoVAZ are considered the most reliable and proven. Almedy Nippon and Trialli have been proven well enough. The cost of the pad bundle is ranging from 700 to 1200 rubles.

Rear pads of low quality, what it leads to

You should not be seduced for cheap products, since different nuances are possible here:

1. Due to poor-quality friction linings, rear brake pads are able to creak.
2. Also as a result of low quality, the brake pads will quickly wear out.

Rear pads, signs of wear, when you need replacement

Replacing the rear brake pads are needed in the following cases:

1. When you click on the brake pedal, the rear brake pads appeared.
2. The rear brakes are not as effective and actually "do not take".
3. The parking brake is not adjustable, the vehicle is not retained on the rise, although the hand brake lever in the car is raised to the maximum.

It is possible that when replacing the rear brake pads, an additional brake system malfunction is found, so before starting work, diagnosis should be diagnosed, at least an external visual inspection.

The car is better to drive into the lift, but it can be examined on the pit. What you need to check:

1. Whether the cylinders do not flow (rear).
2. Status of parking brake cables.

Tools, fixtures, consumables

To replace the tools:

1. Screwdrivers.
2. Wooden bar either from soft metals (brass, copper, bronze).
3. Sledge hammer or hammer.
4. Pliers.
5. Balloon key.
6. A set of car keys (most likely, you will need only the key to "12").
7. WD-40 liquid.

Choosing a workplace

If the replacement lift is not used, then in this case a jack will be required. The pads can be replaced without a hole, but it will not be very convenient to carry out work.

Rear pads, replacement (step by step instruction)

1. To replace the pads, we put the vehicle to the jack and dismantle the rear wheel (if the replacement is carried out not on the lift). In the absence of the lift, it is advisable to make a replacement on the sides alternately - first we make one side completely, then another.
   
2. We unscrew 2 bolts on the "12", which keep the drum and are guide wheels.
3. Next, the rear drum should be dismantled, which is not always dismantled easily. Here, perhaps you will need a sledgehammer or a hammer, brass meal or a wooden bar.
   
4. We remove the springs that tighten the pads. It should be started with side springs, then dismantle the upper and lower. Here will use pliers and screwdriver. Springs are dismantled not so easily (especially the top), most likely, it will have to be pretty tinned with them. Especially hard work without the availability of skills.
5. After removing the springs, the pads are dismantled easily. The parking brake cable is uncovered last.
   
6. The cable for the parking brake cable on new elements is not provided in the kit, so it should be rearranged from old. The bracket is easily rearranged, you should only remove the pin and disconnect the bracket, after which it is installed on a new block and set a pin.
   
7. Now we collect everything back. We begin the assembly from above - we put on the upper spring, the pads fall into the grooves of the brake cylinder and install the strut from above. It is also necessary to and from the bottom to fall into the grooves. Next, we install side springs, and last ones I mount the upper spring.
   
8. Then we install the drum and the wheel, after which we carry out exactly the same work on the other side.
   

Tips Pros: how to remove the rear brake drum, in what cases it is required to replace it

To move the rear brake drum from a place, instead of the guides, you can use other bolts of greater length, but with identical carvings. When twisting bolts, you should not use a lot of effort, otherwise the bolt can be broken. The drum is needed only through the paint or a wooden bar. In addition, it is necessary to do all the surface, and not only on the one hand.

The replacement of the drum must be made if its inner diameter is more than 200.5 millimeters. Meat distance is carried out using a caliper. If after replacing the wheel does not spin, check the assembly correctness. Also make sure whether the parking brake lever is released.
