Check of serviceability of functioning/tightness, replacement and adjustment of the vacuum amplifier of brakes

Check of serviceability of functioning

 PERFORMANCE ORDER

1. Without starting the engine, several times squeeze out a pedal of a foot brake. Make sure of absence of changes in size of a reserve course of a pedal (distance between a pedal and a floor).
2. Holding a pedal squeezed out, start the engine. If right after start the pedal slightly "fails", therefore, the vacuum amplifier of brakes works regularly.

Tightness check

 PERFORMANCE ORDER

1. Start the engine for few minutes, then muffle. Several times slowly squeeze out a pedal of a foot brake. If at first the pedal course with each squeezing is gradually reduced, however, through three-four musclemen is stabilized, means, tightness of assembly of the vacuum amplifier is not broken.
2. Squeeze out a pedal of a foot brake at the working engine. Holding a pedal squeezed out, muffle the engine. If 30 seconds of keeping of a pedal later pressed its reserve course does not change, therefore, tightness of assembly of the vacuum amplifier is not broken.

Check of size of a vystupaniye of a rod of a pusher

 PERFORMANCE ORDER

Remove from the vacuum amplifier GTTs assembly (see. Section Removal and installation of the main brake cylinder).

 Need for a detachment from GTTs of hydraulic lines is absent, - track, that they did not appear are deformed in the course of assembly assignment. By means of the manual vacuum pump create in assembly of the servo-driver of the brake amplifier depression by depth about 508 mm Hg, press on a pusher rod with effort about 2 kgfs and measure length of a vystupaniye of a rod. Compare result of measurement to requirements of Specifications, in case of need replace assembly of the amplifier.

REPLACEMENT

 PERFORMANCE ORDER

The block of the vacuum amplifier of brakes is not subject to regenerative repair and in default should be replaced assembled.

1. Remove GTTs (see. Section Removal and installation of the main brake cylinder).
2. Disconnect the vacuum hose brought to the amplifier from the engine. Try not to damage a hose, removing it from the union on assembly of the amplifier.

3. In salon of the car remove the bottom section of furnish of the panel and find knot of connection of a rod of a pusher of the vacuum amplifier to a pedal of a foot brake (in case of need use a pocket small lamp).

4. Take шплинт, take out a cylindrical pin and disconnect a cutting finger of a pusher from the pedal lever.
5. From salon give four nuts of fastening of assembly of the vacuum amplifier to a partition of an impellent compartment, remove washers (in case of need use a pocket small lamp).
6. Pass to an impellent compartment and remove assembly of the vacuum amplifier from a back partition. Pull assembly strictly on an axis of its installation until the pusher rod completely will not be liberated from a partition. Take assembly from an impellent compartment.
7. Installation is made upside-down (previously check correctness of installation of the adjusting sizes).

ADJUSTMENT

 PERFORMANCE ORDER

Measure distance from a face surface of assembly of the vacuum amplifier to an opening in a cutting finger of a rod of a pusher. Compare result of measurement to requirements of Specifications, in case of need weaken a lock-nut and rotation of a cutting finger achieve demanded value. Do not forget to tighten a lock-nut.
