Adjustment of height of a pedal of a brake over a floor 

Fig. 6.1. Measurement of height of a pedal over a floor: 1–switch of a signal of braking; 2–nut of fastening of the switch of a signal of braking; 3–height of a pedal of a brake; 4–lock nut of a pusher of a pedal of a brake; 5–pusher of a pedal of a brake


Remove a rug of a floor and measure pedal height over a floor (fig. 6.1) . If the height of a pedal does not correspond to norm, execute adjustment, as shown below.
Pedal height over hollow 182,1 (+5,0) mm.
Separate the contact socket of the switch of a signal of braking, unscrew a lock nut of the switch of a signal of braking and wrap it so that it did not concern the lever of a pedal of a brake.

Fig. 6.2. Adjustment of length of a pusher


Unscrew a lock nut of a pusher and adjust height of a pedal of a brake over a floor in the specified limits for what reduce or increase length of a pusher, rotating it пассатижами (fig. 6.2) .
Rotation of the switch of a signal of braking establish a gap between its pusher and a pedal emphasis within 0,5–1,0 mm. Reliably tighten a lock nut of the switch the moment of 8-10 N · m.

       NOTE
The course of a pedal of a brake should make not less than 130 mm.

At a deviation of a course of a pedal from norm repeat adjustment of height of a pedal and a gap between the switch of a signal of braking and a pedal emphasis.
Connect the contact socket of the switch of a signal of braking.
Be convinced that at an otpuskaniye of a pedal of a brake the signal of braking dies away.
At the idle engine dump depression in the vacuum amplifier, two-three times having pressed a brake pedal, and in pressing of a hand check a free wheeling of a pedal of a brake.
The free wheeling of a pedal of a brake should make 3–8 mm.
If a free wheeling of a pedal less than the specified bottom limit, be convinced of compliance to norm of a gap between a pusher of the switch of a signal of braking and an emphasis of a pedal of a brake.
If the free wheeling of a pedal more than the specified top limit, means, the gap between an axis and the lever of a pedal of a brake is too great. Check a technical condition of these details and if necessary replace them.

Check of a technical condition and operability of elements of brake system
Check of a hydraulic actuator of brakes
At the working engine press a brake pedal with effort about 120 kgfs. Check on existence of leaks the main brake cylinder, a hydraulic actuator of brakes and each connection.

Check of operation of the vacuum amplifier of brakes without use of devices
For simple check of operation of the vacuum amplifier it is necessary to execute the following.
Start up the engine, let's to it work 1–2 mines and stop. Several times press a brake pedal with normal effort. If the pedal leaves down at the first
pressing, but gradually rises by the second or third pressing, the amplifier of brakes is serviceable. If the height of a pedal does not change, the amplifier is faulty.
At the idle engine several times press a pedal of a brake and check change of height of a pedal. After that press a pedal and start up the engine. If thus the pedal leaves down a little, the amplifier is serviceable. If the height of a pedal remains former, the amplifier is faulty.
At the working engine press a pedal of a brake and stop the engine. Hold a pedal of a brake pressed during 30 pages. If during this time the height of a pedal does not change, the amplifier is serviceable. If the pedal rises, the amplifier is faulty.
If at one of the specified ways of check malfunction was defined, check a vacuum hose and the amplifier, eliminate malfunctions. If results of all checks positive, the amplifier is serviceable.

Check of operation of the return valve of the vacuum amplifier of brakes
Check carry out on the return valve established in a vacuum hose.

Fig. 6.3. Vacuum amplifier of brakes: 1–vacuum amplifier of brakes; 2–a pressure regulator (on cars without ABS); 3–brake pipelines; 4–vacuum hose


Remove a vacuum hose of the amplifier of brakes (fig. 6.3) .

       NOTE
The return valve is established with a tightness in a vacuum hose on adjusting labels.

Check operation of the return valve by means of the vacuum pump.

PREVENTION
In case of malfunction of the return valve replace it assembled with a vacuum hose.

Air removal from a hydraulic actuator of brakes (pumping)

Fig. 6.4. Tank of a hydraulic actuator of brakes


Remove a stopper of a tank of a hydraulic actuator of brakes and add brake liquid (fig. 6.4) .

PREVENTION
At hit of brake liquid on a paint and varnish covering of a body immediately wash away it.

       NOTE
At air removal from a hydraulic actuator under pressure do not press a brake pedal.


Fig. 6.5. Pumping of a hydraulic actuator of brakes


Attach a vinyl hose to the union for pumping on the wheel cylinder, lower other end of a hose in capacity with brake liquid (fig. 6.5) .
Several times press a brake pedal.
At the pedal pressed to the full weaken an union inhaling for pumping until through a hose brake liquid will not start to follow, then tighten the union.
Repeat listed above action until in liquid following from the brake cylinder there will be no air vials.
Tighten the pumping union.
Moment of an inhaling of unions of pumping of 7-13 N · m.
Execute the specified operations on other wheel cylinders in the following order: a back right wheel (in the direction of movement of the car), a forward left wheel, a back left wheel, a forward right wheel.

Adjustment of the lever of a drive of lay brake system 
After pumping of a hydraulic actuator of brakes of 20 times press a brake pedal with effort more than 10 kgfs.
More than three times to the full tighten the lever of a drive of the parking brake.

Fig. 6.6. Lever of the parking brake: 1–lever of the parking brake; 2–adjusting nut; 3–cable of a drive of the parking brake; 4–equalizer; 5–casing


When lifting the lever should move on 6–8 teeth of sector (the point of the appendix of effort should settle down at distance of 25 mm from a lever end face). When moving  on bigger or smaller number of a teeth of sector adjust a lever course (fig. 6.6) .
The control lamp of turning on of the parking brake dies away at complete switching off of a brake and lights up when lifting lever on one tooth of sector. If the switch does not operate, as is specified, replace it.
Upon termination of adjustment be convinced of lack of a pritormazhivaniye of back wheels at completely lowered lever of a drive of the parking brake.
