12.3. Replacement of blocks of disk brake mechanisms
|
|
It is necessary to replace disk brake shoes on both wheels at the same time - NEVER replace blocks only on one wheel. Besides, the dust created by brake system, can contain the asbestos harmful to your health. Never delete it by means of the compressed air and do not inhale it. At work with brakes it is necessary to put on a special filtering mask. Never, under no circumstances, use solvents on the basis of gasoline for washing of details of brakes. Use only a cleaner of brake system! At service of disk brakes use only original or high-quality firm brake shoes. |
|
|
The procedure described below belongs both to lobbies, and to back disk brake mechanisms. |
|
|
- Uncover (covers) the tank with brake liquid and merge about two thirds of liquid from the tank. If you do not make it, liquid will be poured from the tank at pressing in of pistons of a support in their openings.
- Release bolts of fastening of wheels, поддомкратьте a front or a back of the car and reliably establish it on axial support.
- Remove lobbies or back wheels, necessarily. Work with each party of brakes in turn that the collected party if necessary could serve as a sample at assembly.
- Attentively survey a brake disk as it is described in the Section Survey, removal and installation of a brake disk. If machining is required, remove a disk as it is described in the same Section, thus it is possible to remove blocks from supports also.
- Following descriptions on illustrations below, make procedure of removal of brake shoes.
|
|
Here the photos describing procedure for back supports are not provided; differing on the size a little, on a design they are identical to forward brake supports.
|
|
|
Some models can have excellent from shown in this Chapter of number and types of protivovizgovy laying and other details. Before dismantling it is necessary to pay attention to, how details are established in the car further to have possibility correctly to collect them. |
|
|
- Disconnect the electric socket of the sensor of wear of a brake shoe.
|
|
|
- Remove caps from bolts of fastening of a brake support and give bolts.
|
|
|
- Take a protivovizgovy spring.
|
|
|
- Push through the piston With-shaped........
|
|
|
- Remove a support and an internal brake shoe.
|
|
|
- Remove an internal brake shoe from the piston.
|
|
|
- Suspend a support on a piece of a wire that it did not disturb work.
|
|
|
- Remove an external brake shoe - to establish new blocks, repeat procedure upside-down.
|
- Do not forget to examine sensors of wear of blocks (only a forward left wheel, or forward left and back right a wheel). If they as it should be, reinstall them from old blocks on the new; if they wore out from a friction, establish new sensors on new blocks.
- Installation of new blocks repeats removal procedure upside-down. At installation of a support make sure that all fixing bolts are tightened with demanded effort.
- On termination of work strongly squeeze out a brake pedal several times to bring blocks into contact with disks. The pedal should be at normal height from a floor and not sink down. Check level of brake liquid and if necessary add it in the tank. Carefully check, whether there are no leakages of liquid and whether brakes before the beginning of normal operation of the car well work.
- Whenever possible avoid sharp braking the first 80-100 km of run while new blocks will not get used to a place.
