6.1.13. Amplifier of brakes

ATTENTION
Never sort the amplifier of brakes. Dismantling will break normal work. If the amplifier is faulty, replace him new.

Fig. 6.26. Details of the amplifier of brakes: 1 – vacuum amplifier; 2 – laying; 3 – hose of the vacuum amplifier of brakes; 4 – a pin with a head and an opening under the forelock; 5 – clip; 6 – nut; 7 – a pin lock-nut with a head and an opening under the forelock (left); 8 – a pin lock-nut with a head and an opening under the forelock (right); 9 – pusher fork; 10 – main brake cylinder; 11 – nut of fastening of the main cylinder



NOTE
In the figure 6.26 the car with the left arrangement of steering is shown.

Check of operation of the amplifier
There are two ways of check: with a tester and without it. Usually, it is possible to define roughly a condition of the amplifier without using a tester.

NOTE
When performing check make sure that in the brake pipeline there is no air.

Tightness check
Start the engine.
To stop the engine after 1–2 min. work.

Fig. 6.27. Check of tightness of the amplifier of brakes


Nazhimite on a brake pedal several times with the same loading, as well as at ordinary braking also you watch the pedal course. If the pedal course with each pressing decreases, the amplifier is tight (fig. 6.27).

Fig. 6.28. Change (fall) of the course of a pedal


If the course of a pedal does not change, the amplifier is not tight (fig. 6.28).

NOTE
If malfunction is found, check vacuum highways and laying, replace all defective parts. After that repeat all check.

Work check

Fig. 6.29. Check of change of the course of a pedal


At the stopped engine press a brake pedal several times with identical effort and make sure that the course of a pedal does not change (fig. 6.29).

Fig. 6.30. "Small" course of a pedal


To start the engine at the pressed brake pedal. If the pedal course increases a little, the amplifier is efficient. The invariable course of a pedal does not indicate malfunction (fig. 6.30).

Check of tightness under loading

Fig. 6.31. Keeping of a pedal


Press a brake pedal at the working engine. Stop the engine holding a pedal of a brake pressed (fig. 6.31).
H: Hold

Fig. 6.32. Check of tightness under loading


Hold a pedal of a brake pressed during 30 pages. If pedal height over a floor does not change, the amplifier is efficient. The amplifier is disabled if the pedal rises (fig. 6.32).
