Service of drum-type brake mechanisms of back wheels
|
|
For rubbing of components of brake mechanisms it is necessary to use special means, or methyl alcohol, - at all do not apply solvents on an oil basis! |
Design of the drum-type brake mechanism of a back wheel
Dismantling
|
|
Unscrew nuts of fastening of a brake drum to a semi-axis flange.
|
|
Screw-driver rotating a regulator through a service opening, take away boots from drum walls, then turn out the fixing screw and remove a drum.
|
|
|
By means of nippers remove a spring of the adjusting lever.
|
|
|
Remove the adjusting lever.
|
|
|
Remove the top coupling spring.
|
|
|
Having turned clockwise a regulator of a razzhimny level, remove the last.
|
|
|
Develop an anchor finger parallel to a flute and remove directing springs of boots.
|
|
|
Remove the bottom coupling spring.
|
|
|
By means of nippers disconnect a driving cable from the executive lever of the parking brake.
|
|
|
Disconnect a hydraulic hose from the back party of a brake board, then turn out pair of fixing bolts and remove the wheel cylinder.
|
|
|
In case of need disassemble the wheel cylinder on components (two boots, two pistons, two piston cups, a razzhimny spring).
|
|
|
Assessment of a condition of components
|
|
Carefully smooth out all removed components and attentively study their general condition. Defective details replace.
|
|
Define degree of wear of frictional overlays of boots, in case of need make replacement.
|
|
|
It is necessary to replace boots in a set for both wheels of a back axis! |
Check a working surface of drums on existence of signs of an overheat, cracks, задиров and other mechanical damages. Insignificant defects can be eliminated with a way of processing by a fine-grained emery paper, or a frictional surface of an old brake boot. In case of identification of deep damages give drums to a pro-point (within an admissible range), or make their replacement.

|
Assembly
|
|
|
|
According to instructions grease working elements of the wheel cylinder and make assembly of the last.
|
|
|
Assembly is made as it should be, the return to an order of dismantle of components, - track, that the lever of automatic adjustment correctly nestled on a regulator cogwheel. Do not forget to grease a point of fastening of springs, track observance of requirements of Specifications of Head Brake system to efforts of a tightening of carving fixture.
|
|
|
Before installation to the place of a drum measure external diameter of assembly of the boots planted on a brake board, then measure internal diameter of a drum. By subtraction of result of the first measurement from result of the second define size люфта landings of boots, - the result of calculation should not fall outside the limits an admissible range.
