The vacuum amplifier of brakes increases the effort made for a brake pedal, facilitating thereby driving. The principle of 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 a brake pedal in the middle of its course and start the engine. At the serviceable vacuum amplifier the brake pedal after launch of the engine has to go down. If the pedal does not leave, check fastening of a tip of a vacuum hose, connection of a flange of a tip in the amplifier, a condition of a hose and the union.
Wait two minutes and switch off the engine. Press a brake pedal. With each next pressing the pedal has to become is firmer, and the course of a pedal to decrease.
