Removal

 PERFORMANCE ORDER

  1. To change the provision of a disk of a wheel concerning a nave that it was possible to establish an otbalansirovanny wheel in former situation.
  2. To weaken nuts of a wheel of the car standing on the earth.
  3. To lift a back part of the car.

Thus the piston should not be pulled out. To check, whether it is damp behind a boot. If necessary to repair the wheel cylinder.

  1. To put on a boot the wheel cylinder.

Installation

It is obligatory to replace all 4 brake shoes even if the limit of wear were reached only by one. To use blocks of one brand. To clear a brake drum and a brake board the vacuum cleaner or alcohol. If the wheel brake cylinder damp to replace it. Slightly to grease the adjusting device with MoS2 greasing. To chisel the drums having grooves, thus always to process both drums. Brake drums can be chiseled till the maximum diameter of 201 mm.


 PERFORMANCE ORDER

  1. Insignificant roughnesses and traces of a rust to eliminate with a small emery paper.
  1. To clear six surfaces of contact between brake shoes and a board of a brake and before installation of blocks to cover with a thin layer of heat resisting greasing, it is best of all high-temperature copper paste.
  1. To attach springs to the adjusting device and brake shoes.
  1. Before installation of brake shoes to shift a segment of the adjusting device while it will not adjoin to a brake board. At the expense of it the distance of blocks is established on the smallest value. For moving of a segment to insert a screw-driver between a finger and a segment and to turn it in the arrow direction. Type of a brake from above.
  1. To insert brake shoes at first in the bottom of, opposite to the wheel cylinder. To establish the adjusting device from above between blocks and at the same time to establish blocks on both parties of the wheel cylinder.

Not to load the wheel cylinder only on the one hand, differently the piston will be squeezed out on the other hand.

  1. To attach to the lever a cable of the hand brake.
  1. To establish on a brake board back and forward blocks and to fix a pin of fastening and a clamping spring. Thus holding a pin behind, at the same time to press a spring flat-nose pliers and to turn on 90 °.
  1. To check operation of the device of automatic adjustment. For this purpose 2-3 times to squeeze out a pedal brakes (assistant). Thus the adjusting segment should move. If it does not occur, means, brake shoes were incorrectly established.
  2. To establish the adjustment device for the smallest adjustable length.
  3. To establish a brake drum and to screw a new nut of a nave.
  4. To adjust люфт the nave bearing.

To stop a nut after adjustment, see. Head Suspension bracket and steering system.

  1. To screw a wheel, thus to watch a label on a nave. To lower the car and to tighten wheel nuts cross-wise with effort of 100 Nanometers.
  2. To adjust the main gap of back brakes in several pressing of a pedal of a brake. Thus in a brake clicks are audible.
  3. To adjust the hand brake.
  4. To make trial braking on average speed on the free road from transport.

Cars from 10/89 g вып., except the versatile person model

1 — a fastening bolt
2 — a brake drum
3 — a returnable spring
4 — a pin of fastening and a spring
5 — a protivoskripny spring
6 — a brake shoe
7 — a brake shoe
8 — a persistent spring and a bracket

9 — a returnable spring
10 — a cable of the hand brake
11 — the driving lever
12 — the brake pipeline
13 — a bolt of the wheel brake cylinder
14 — the wheel brake cylinder
15 — laying

to grease (high-temperature paste)

To remove details as numbers. Separate elements of the right and left brakes differ from each other; they cannot replace each other.
