9.5. Assembly of the main cylinder of a brake

Before assembly it is attentive to examine and be convinced of absolute purity of "mirror" of the main cylinder and the working surface of pistons, of lack of a rust, рисок and other roughnesses.

For elimination of defects on "mirror" of the main cylinder its honingovaniye is allowed, however at the same time diameter of "mirror" of the main cylinder should not exceed a certain size.

At the defects causing significant increase in diameter of "mirror" of the main cylinder, its case should be replaced new.

At each dismantling of the main cylinder it is necessary to replace cuffs even if by the form they in good shape.

To check elasticity of springs of pistons. To wash out all details pure brake fluid.


Prevention

Hit of mineral oils, gasoline, kerosene or diesel fuel on a detail since even traces of these liquids can lead to destruction of rubber cuffs is not allowed.
