GENERAL INFORMATION

The vacuum amplifier of brakes reduces effort on a brake pedal, facilitating thereby driving. Operation of the vacuum amplifier of brakes is based on use of depression in an inlet collector. At an exit of the vacuum amplifier out of operation operability of the brake system is not broken, but for pressing of a pedal of a brake it is necessary to make considerably bigger effort.

Press a brake pedal several times at the idle engine to create the identical pressure close to atmospheric in cavities of the vacuum amplifier. At the same time determine by the effort enclosed to a pedal whether there is no jamming of the case of the valve. Stop brake loops in the middle of its course and start the engine. At the serviceable vacuum amplifier the brake pedal after start of the engine has to leave forward. If the pedal does not leave forward, check fastening of a tip of a hose, connection of fastening of a flange of a tip in the amplifier, a condition of a hose and the union. On cars with diesel engines check operability of the vacuum pump.
