12.15. The vacuum amplifier of brakes

The vacuum amplifier

1 – the main brake cylinder,

2 – the vacuum amplifier,

3 – an arm of fastening of a tank,

4 – a tank of a brake liquid


1. To press a brake pedal some times at the idle engine, to create in cavities of the vacuum amplifier identical pressure close to the atmospheric.
2. Simultaneously on the effort put to a pedal to define, whether there is no jamming of the case of the valve.
3. To stop a pedal of a brake in the middle of its course and to start the engine.
4. At the serviceable vacuum amplifier the pedal of a brake after engine start-up should leave forward.
5. If the pedal does not leave forward, to check up fastening of a tip of a hose, a condition of fastening of a flange of a tip in the amplifier, a hose and union condition.
