10.8. Vacuum amplifier of brakes

The vacuum amplifier of brakes does not demand special service, except the routine technical inspection of hoses and the air filter in the bottom of a cover near a brake pedal pusher end face.
Repair of the vacuum amplifier of brakes is not provided therefore at emergence of malfunctions it needs to be replaced.
Turn off nuts of fastening of the main brake cylinder on the vacuum amplifier of brakes. Disconnect the socket of the sensor of level of brake fluid and take the main brake cylinder aside. Do not bend the brake tubes going to the main brake cylinder. If there are any doubts concerning flexibility of tubes, disconnect them from the main brake cylinder and close the ends traffic jams.

Fig. 10.20. Elements of fastening of the vacuum amplifier of brakes: 1 – a pin with a head and an opening under the forelock; 2 – fork and nut; 3 – forelock; 4 – laying; 5 – vacuum amplifier of brakes; 6 – socket of the sensor of level of brake fluid; 7 – main brake cylinder; 8 – brake tubes; 9 – nut; 10 – vacuum hose; 11 – collar


Disconnect a vacuum hose from a forward part of the vacuum amplifier of brakes (fig. 10.20).
In interior of the car remove a heater fan air duct from under the dashboard and the lower finishing. Remove the forelock and a pin with a head and an opening under the forelock, disconnect a pusher of the vacuum amplifier of brakes from a brake pedal. At a detachment do not reject a pusher aside.
Turn off four nuts of fastening of the vacuum amplifier and accurately take it from a motor compartment.
If the new vacuum amplifier of brakes is required to establish, check a gap between primary piston of the main brake cylinder and a pusher of the amplifier.
At installation freely screw four nuts and connect a pusher to a brake pedal. Tighten nuts and connect a vacuum hose. If brake tubes of hydraulic system were disconnected, completely pump over the brake system for removal of air which got to it.
Check height of installation and a free wheeling of a pedal of a brake and if necessary adjust them.
