Check of the amplifier of a brake

Check operation of the amplifier of a brake if for achievement of necessary braking it is required to put excessively big effort to a brake pedal.

1 At the idle engine press a brake pedal not less than 10 times, then at the pressed pedal start the engine. Now the pedal of a brake has to move noticeably. In this case the amplifier is serviceable.
2 Otherwise disconnect a vacuum hose at the amplifier and start the engine. Apply a finger to the end of a hose and check whether there is a vacuum.
3 If there is no vacuum: Check a vacuum hose for tightness and existence of damages, if necessary replace it. Delay fastening of all collars.
4 Diesel engine: Disconnect a vacuum hose from the vacuum pump and check a finger whether there is a vacuum. The vacuum pump is fixed to a head of cylinders.
5 If vacuum is available: Measure value of vacuum, if necessary replace the amplifier of a brake (work HUNDRED).

At the petrol engine surely replace also backpressure valve in the vacuum pipeline as the diaphragm in the amplifier of a brake at the faulty backpressure valve owing to the getting vapors of fuel can be damaged.
