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

Replacement

8. On brakes with a vertical arrangement of blocks take away the 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 °.

26. Clear a drum and check a condition of a surface.
27. Check ovality of a drum, at strong damages pierce a drum, small roughnesses are ground by a skin.
28. If after a pro-point the internal diameter of a drum appears more limit (it is specified on a drum), replace a drum.
29. Install the reel and check adjustment of a brake.
30. If the gap between blocks and a drum is too big, then remove a drum and rotating a wheel of a hairpin part blocks to a contact of a surface of the reel.
