Check, removal and installation of the block of the vacuum amplifier

 CHECK

1. To check up serviceability of the amplifier, press a brake pedal some times to dump vacuum, then start the engine, keeping a pedal of the pressed. At start of the engine the pedal should be displaced aloud downwards. Allow to the engine to work two minutes, then switch off it. Again press a brake pedal some times - the pedal course should decrease now with each pressing.
2. If the amplifier works not as is described, examine the unidirectional valve (address to Section Removal, check and installation of the unilateral valve of the block of the vacuum amplifier). If the valve functions correctly, replace the air filter of the amplifier (address to paragraph 6 more low).
3. If the amplifier continues to work with failures, the block is damaged. To repair the block it is impossible, it is necessary to replace it.


 REMOVAL

1. Remove the main cylinder as Removal, a partition and installation of the main cylinder is described in Section.
2. Disconnect a vacuum hose from the unidirectional valve of the amplifier.
3. Working in salon, let out fixing скобы and remove from the instrument panel the bottom cover (where is available) on the party of the driver.

4. Pull out fixing скобу and remove a pin of a plug of a pusher (address to an accompanying illustration).

5. Loosen the also remove four fixing nuts, then return to an impellent compartment and deduce the amplifier together with a lining from working position (address to an accompanying illustration). The lining should be replaced, if it is worn out or damaged.

6. If the amplifier is faulty, replace it is a block partition it is impossible. The unique component which is on sale separately is an air filter of the amplifier. To replace the filter, separate a rubber protective cover from a back part of the amplifier, displace it on a bar-pusher, then accurately unhook from the amplifier. Make on the new filter a cut (A) (address to an accompanying illustration). Place the filter on a bar-pusher (F), shift it into position, then establish a rubber cover.


 INSTALLATION

1. Before amplifier installation be convinced that the end of resulting draught will defend from a forward end face of the amplifier on 223 mm (X), and a pin of a plug of a pusher (C) from a back end face of the block - on 133 mm (L) (address to an accompanying illustration). To adjust length of the end of the bar-pusher turned to a pedal of a brake, ослабьте a plug counternut (P) and rotate a plug, yet will not achieve the necessary result. Tighten a counternut. To adjust distance between the end of a pusher and the main cylinder, simply rotate a nut on the bar-pusher end.

2. Clear and dry all contact surfaces and establish a lining on a back part of the amplifier. Deduce the amplifier into position and establish it in a partition.
3. Working in salon, be convinced that the amplifier costs level with a brake pedal, then establish fixing nuts and tighten their effort resulted in Specifications.
4. Level a plug of a bar-pusher with a pedal of a brake and insert a pin. Attach a pin скобой. Establish on the instrument panel the bottom cover.
5. Working in an impellent compartment, connect a vacuum hose to the amplifier.
6. Establish the main cylinder as Removal, a partition and installation of the main cylinder is described in Section and pump over all brake system (address to Section Prorolling of hydrosystem of brakes).
