Installation make in sequence, return to removal, taking into account the following.

If the new vacuum amplifier is established, check a pusher gap as follows:

Fig. 11.40. Measurement of a vystupaniye of a pusher of the vacuum amplifier of brakes (size A)

– measure distance on which the pusher of the vacuum amplifier of brakes from a privalochny surface of the main brake cylinder (fig. 11.40) acts , and write down it as the size A;

– measure distance from a flange end face to a privalochny surface of the main brake cylinder and write down it as the size B;

– measure distance from a flange to the piston of the main brake cylinder and write down it as the size C;

Fig. 11.41. A gap between a pusher (2) vacuum amplifiers of brakes and the piston (1) main thing of the brake cylinder: X = 0 mm

– subtract the size B from the size A, then from the received value (And — In) subtract the size C and receive a gap X (fig. 11.41) of a pusher 2 which should be equal 0. If the gap size negative, i.e. presses a pusher of the vacuum amplifier the piston of 1 main thing of the brake cylinder, there will be a constant pritormazhivaniye of wheels. If there is a gap, when braking the course of a pedal of a brake will increase.

If the size of a gap does not correspond to demanded value, adjust it, changing length of a pusher. Passatizhami hold a pusher of the vacuum amplifier of brakes from a provorachivaniye and a wrench screw or turn out a pusher head.

After installation of the main brake cylinder and connection to it brake tubes adjust height of installation of a pedal of a brake and remove air from hydraulic brake system.
