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.

Installation

PERFORMANCE ORDER
1. Installation is carried out upside-down. Replace шплинт axes. Adjust a brake pedal.
2. If the new unit adjust выступание a pusher of the main cylinder over the amplifier case is established. 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. On the other hand the pusher should not rest against the piston as braking will be incomplete excessively.
4. Measure distance from an end face of the main cylinder to a flange. It is the size of Century
5. Measure distance from a cylinder end face to the bottom piston dredging. It is the size With.
6. The backlash between a pusher and the piston is equal (In-) - A.Otregulirujte выступание a pusher, rotating a pusher tip. Establish such выступание And that the backlash was equal 0.
