8.6. Blocks of drum-type brakes

GENERAL INFORMATION

Installation of the party of a block And


1. Left wheel
2. Right wheel
3. To a forward part of the car

The provision of blocks after assembly

1. Left wheel
2. Right wheel
3. To a forward part of the car

Prevention

Blocks change only in a set on one axis.


Together with blocks coupling springs which, being exposed to periodic thermal loadings change also, gradually lose elasticity and do not provide sufficient branch of a block from a drum. As a result the drum touches blocks, causing their premature wear.

Replacement

PERFORMANCE ORDER
1. Release nuts of wheels, lift back (or a lobby) a part of the car.
2. Remove wheels.
3. Release the hand brake.

6. If this measure does not give result, reduce blocks.
7. For this purpose on brakes with a horizontal arrangement of blocks get a cap from a board of a brake and rotate a regulator cogwheel a screw-driver.
8. On brakes with a vertical arrangement of blocks take away a screw-driver with a narrow edge the regulator lever from a cogwheel and rotate a regulator cogwheel other screw-driver.
Brake with horizontally located blocks
9. Remove a coupling spring.
10. Remove clamping springs of blocks, having pressed a cup and having turned on 90 °.
11. Remove blocks together with the bottom spring.

24. Establish blocks upside-down.
25. The provision of blocks after assembly should look definitely (see fig. The provision of blocks after assembly).
26. Clear a drum and check a surface condition.
27. Check ovality of a drum, at strong damages a drum pierce, small roughnesses are ground by a skin.
28. If after a pro-point internal diameter of a drum appears more limiting (it is specified on a drum), a drum replace.
29. Establish a drum and check brake adjustment.
30. If the gap between blocks and a drum is too great, remove a drum and rotating a wheel of a hairpin dissolve blocks to a contact of a surface of a drum.
