8.13. The vacuum amplifier of brakes Check

PERFORMANCE ORDER

1. While in service care of this unit it is not required. It is necessary to check only a condition of a hose and the amplifier case. 2. For check of work of the amplifier some times press a brake pedal on the idle engine. The pedal course by each pressing should not to vary (is checked on distance to a floor). 3. Press a pedal and start the engine, – the pedal should be displaced a little forward. 4. Start the engine, later 1–2 mines stop. With force press a pedal some times, – the pedal course should decrease gradually. 5. Start the engine and press a pedal. Keeping a pedal pressed, stop the engine, – during 30 сек after a stop pedal position should not to vary. 6. If the amplifier is faulty, he will lie down to replacement.

Removal

PERFORMANCE ORDER

1. Disconnect from the amplifier a hose (it is specified by an arrow). 2. Turn away a nut of the main cylinder and cautiously remove the cylinder from hairpins. 3. In salon расшплинтуйте an axis also unhook a pedal spring (the axis of a pusher and a spring are specified by arrows). Get an axis and disconnect a plug of a pusher from a pedal. 4. Turn away a nut of fastening of the amplifier (are specified by arrows) to a partition of a motor compartment. 5. Cautiously submit the amplifier and remove when hairpins leave a partition.

For this purpose execute the following. 3. Measure выступание a pusher taking into account a lining (1 backlash). It is the size A.Zazora between a pusher and the cylinder piston should not be, the course of a pedal of a brake otherwise increases.
