10.3. Removal, dismantling and installation of a brake bracket
Brake bracket
Removal of the brake mechanism of wheels
Brake mechanism of forward wheels
|
- Prepare the car and remove the necessary forward wheel.
- Remove brake shoes (as it is specified earlier).
- Turn off a cover of a tank of brake fluid of the main brake cylinder, enclose under it laying from sheet polyethylene, densely screw a cover to reduce losses of liquid at further operations.
- Turn off a bolt of fastening of the sensor of wear of blocks from a support.
- Weaken connection of a brake hose on a brake bracket.
- Turn out bolts of fastening and remove a brake bracket from a rotary fist, turn off nipple connection of a flexible hose.
- For removal of the brake mechanism of back wheels operations are performed similarly, only lift a back part of the car and remove a brake bracket from a wheel nave.

Dismantling
|
Control of provision of bore |
|
- Remove dustproof caps, but do not damage a napressovanny ring.
- Air pressure from the tire pump connected to the entrance union of a hydraulic actuator on a brake bracket put forward one of pistons, holding the opposite piston.
- Having blocked an opening of the taken-out piston (thick rubber), similarly put forward the second piston.
- Mark pistons and the corresponding cylinders that at assembly not to mix.
- Make fault detection of a surface of pistons and cylinders. Existence of zadir, a holding strap, attritions demands replacement of all brake bracket.
- Take out sealing rings from flutes of cylinders and establish new sealing rings, having cleaned them pure brake fluid. Rings are established manually.
- Grease pistons with brake fluid and insert them into the corresponding cylinders. Turn pistons so that their bores settled down at an angle 20 ° rather lower part of a bracket, and carry out an inspection of their situation a template.
- Move pistons against the stop and establish dustproof caps.
- Heat-shielding caps be also convinced by Napressuyte that a driving part of the piston acts not less, than on 0,1 mm over a surface of a heat-shielding cap. Caps of external and internal pistons are various and are not interchanged.
- Installation is carried out as it should be, the return to removal. Carry out removal of air from a hydraulic actuator.
