Installation make in sequence, return to removal, taking into account the following.
If the new vacuum amplifier check up a pusher backlash as follows is established:
Fig. 11.40. Measurement выступания a pusher of the vacuum amplifier of brakes (size)
– Measure distance on which the pusher of the vacuum amplifier of brakes from привалочной
surfaces of the main brake cylinder (fig. 11.40
), and write down it as the size And;
– Measure distance from an end face of a flange to привалочной surfaces of the main brake cylinder and write down it as the size In;
– Measure distance from a flange to the piston of the main brake cylinder and write down it as the size With;
Fig. 11.41. A backlash between a pusher (2) vacuum amplifiers of brakes and the piston (1) main brake cylinders: Х = 0 mm
– Subtract the size In from the size And, then from the received value (And—) subtract the size With and receive backlash Х
) a pusher 2 which should be equal 0. If the backlash size negative, i.e. presses a pusher of the vacuum amplifier the piston of 1 main brake cylinder will occur constant притормаживание
wheels. If there is a backlash at braking the course of a pedal of a brake will increase.
If the backlash size does not correspond to demanded value adjust it, changing length of a pusher. Пассатижами keep a pusher of the vacuum amplifier of brakes from проворачивания and a wrench screw or turn out a pusher head.
After installation of the main brake cylinder and connection to it of brake tubes adjust height of installation of a pedal of a brake and remove air from hydraulic brake system.
