Disk brakes of back wheels

THE GENERAL DATA

Here supports have the same execution, as on forward wheels. Except for resulted below the description, other works are spent to similarly brake mechanism of forward wheels.

REMOVAL AND INSTALLATION BRAKE КОЛОДОК

Instructions on removal and installation brake колодок the forward brake mechanism, resulted in Section 2, operate in the relation колодок disk brakes of the back brake mechanism. Difference consists in the moment of an inhaling of bolts of fastening which in this case makes 44 Nanometers.

PERFORMANCE ORDER
1. At assemblage press the piston into a cylinder aperture just as it is shown. Thus it is necessary to watch liquid level in a tank.
2. Establish clips and washers on directing колодок and establish on the right and at the left brake колодки.
3. The deterioration index in the bottom part brake колодок should specify inside. Establish a support
4. In summary fill in a brake liquid in a tank of the main cylinder and some times press a brake pedal that brake колодки have occupied correct position.

Brake колодки extra earnings demand. Therefore it is not necessary to press sharply a brake pedal in an operation initial stage.

REMOVAL, REPAIR AND SUPPORT INSTALLATION

There is a repair complete set of a support. At its absence it is necessary to replace a support. Excepting some details, as a whole a support looks like, shown on an illustration.

Details скобы a forward brake of the car from the middle of 1995 of release
1 - a protective cover
2 - the union for air removal
3 - a lock ring
4 - a dustproof ring
5 - the piston
6 - a cuff
7 - a support

At support repair it is necessary to be guided by the instructions resulted in subsection 12.1.2 for a support of the car from the middle of 1995 of release.

SUPPORT INSTALLATION

In the presence of any outer defects of consolidations of joining of their brake hose it is necessary to replace.

PERFORMANCE ORDER
1. If directing колодок has been removed, establish and fix its bolts on a semiaxis casing.
2. Bolts tighten the moment of 104 Nanometers.
3. Attach a brake hose to a support, watching correctness of position of a hose. The directing finger should enter into a support aperture.
4. A hollow bolt of joining of a brake hose tighten the moment of 35 Nanometers.
5. Unions of removal of air tighten the moment of 8 Nanometers and are closed by caps.
6. Again establish brake колодки as it is described above.
7. Remove polyethylene from a mouth of a jellied aperture of a tank of the main cylinder.
8. Add if necessary a brake liquid and wrap a tank stopper.
9. Other works are spent to sequences, return to removal.
10. Remove air from brake system as it is described more low.
11. After assemblage check up system on tightness.
12. Check up action of brake system in the course of car movement.

Before removal of a brake disk it is necessary for checking up on palpation, since. The disk can be deformed. The brake disk fastens a bolt with head Torx. However the bolt completely does not press a disk to a wheel nave. For maintenance full прилегания one of bolts of fastening of a wheel is rolled with the remote plug in a nave opposite to a bolt of fastening of a brake disk and clamps a nave. Thus uniform fastening on the right and at the left is reached.
Disk check on palpation is made according to the description resulted in Section 2. Brake disks can be ground if necessary. The minimum admissible thickness of a disk is resulted in Specifications.
The brake disk acts in film as follows:

PERFORMANCE ORDER
1. If the wheel is already removed, as it was accepted above, turn out a bolt of fastening of the wheel, used at palpation check.
2. Remove a brake disk and as it has been described in Section 2 adhere a support a wire to the chassis.
3. Turn out both bolts and disconnect directing from a brake disk.
4. Turn out a special key a fastening bolt in a face surface of a brake disk. The bolt has a head "Torx".
5. Remove a brake disk from a wheel nave. If necessary for this purpose it is possible to take advantage of a rubber hammer.

Before installation of a brake disk smooth out small наждачной a skin interfaced surfaces of a disk and a wheel nave. If the new brake disk is established, it is necessary for clearing of greasing.

PERFORMANCE ORDER
1. Establish a brake disk and обстучите its rubber hammer.
2. Screw and tighten a fastening bolt.
3. Check up a brake disk on palpation as it is described above.
4. Unexpectedly appeared palpation can be a consequence of hit of extraneous particles between planes of interface of a disk and a nave. Then again disassemble connection, clear and collect.
5. Establish directing and tighten bolts of its fastening by the moment of 104 Nanometers.
6. Establish brake колодки as it is described in Section 2, observing the moment of an inhaling of directing fingers. On back supports directing fingers fasten the moment of 44 Nanometers.
7. Lower the car on wheels and tighten bolts of fastening of wheels the moment of 110 Nanometers.
The prevention
Wheel disks from easy alloys fasten the moment of 120 Nanometers.


Instructions

The thickness of brake disks can be measured without their removal. It becomes a calliper, as shown. Keep in mind distinction in executions.

REPLACEMENT OF THE CASING OF THE BRAKE DISK

Replacement of a casing of a brake disk by back wheels differs from the same operation on forward wheels owing to presence of a lay brake. Work is carried out in the image described more low. The description of separate operations is resulted in corresponding subsections.

PERFORMANCE ORDER
1. Remove a brake support.
2. Remove a brake disk.
3. Remove details of a lay brake.
4. Brake колодку with a cable cast away downwards and disconnect a cable.
5. Remove directing колодок as it is described in Chapter 10 for execution with disk brakes.

REPLACEMENT BRAKE КОЛОДОК THE LAY BRAKE

At disk brakes the lay brake is put in action by means of pressing brake колодок to a brake disk at influence on the lever of a drive of a lay brake. Details of a lay brake at disk back brakes are shown on an illustration.

The scheme of assemblage brake колодок a lay brake at disk brakes


PERFORMANCE ORDER
1. Remove a support (1).
2. Remove a back brake disk (2).
3. Now the brake is well visible. Clear the mechanism a rag.
4. Press a finger of a hand from an underside of a brake board on анкерный a pin (3) and clamp flat-nose pliers a spring plate in front of brake колодки just as it is shown, for a drum-type brake.
5. Press a plate and turn a pin so that it was possible to spend a head through a spring plate.
6. Remove a plate, a spring and a pin.
7. Work execute on both brake колодках.
8. Removal of a spring (2) is shown on an illustration.
9. Take out a pin (3) from an underside of a brake board.
10. Nippers remove the top spring (4) on the one hand, as shown.
11. A screw-driver remove the bottom coupling spring (5).
12. Remove brake колодку (6).
13. Take away downwards brake колодку, as shown, and disconnect a cable from the lever of a drive of a lay brake. It is necessary to remember an arrangement of springs and the adjusting mechanism, since. Adjusting маховичок should be on the certain party.
14. Measure internal diameter of a brake disk. If it exceeds 211.4 mm, it is necessary to replace a brake disk. The rating value of diameter makes 210 mm.
15. Carefully clear all details.
16. Develop an adjusting bar, oil and some times curtail and develop.
17. In summary curtail a bar for the minimum length.
18. Slightly grease on a brake board of a place of interface with brake колодками.
19. Fix on анкерном a pin one of brake колодок on a brake board.
20. Establish the lever of a drive of a lay brake and establish the second brake колодку similarly the first.
21. Establish springs and an adjusting bar.
22. Hook on the top coupling spring between колодками.
23. Establish a brake drum/disk and adjust a lay brake as it is described more low.
24. Other works spend to sequences, return to removal.
