Condition check, removal and installation of a brake disk
|
Procedure is equally applicable to disk brake mechanisms both forward, and back wheels. |
Condition check
|
1. Weaken nuts of fastening of wheels, поддомкратьте the car and establish it on props. Remove the corresponding wheel, then screw pair of wheel nuts back on fixing hairpins, having enclosed under them washers in thickness of 3 mm for the purpose of fixing of a brake disk. At check of a disk of the back brake mechanism do not forget to release the parking brake.
|
3. Make visual check of a condition of both working surfaces of a disk. Easy defects can be eliminated by means of a fine-grained emery paper. For removal of furrows by depth a disk it is necessary to remove and subject more than 1.0 mm to a pro-point. Remember that survey of a disk should be made from its both parties. |
4. If during braking pedal pulsations were noticed, it is necessary to estimate size of lateral palpation of a brake disk. Fix a tsiferblatny measuring instrument of plunzherny type (DTI) at distance about 12.7 mm from external edge of a disk. Null the device and start to rotate a disk. The result of measurement should not fall outside the limits the admissible range stipulated in Specifications, otherwise it is necessary to give a disk to a pro-point.
|
Originators of the real Management recommend to make a pro-point of disks regardless of their condition for the purpose of removal from working any surfaces of defects. As a last resort it is possible to be limited to disk processing by a fine-grained emery paper. |
|
5. At a pro-point of a disk it is necessary to give particular attention to observance of requirements of Specifications to its minimum admissible thickness. On a face surface of a disk the corresponding marking is provided. Measurement of thickness of a disk is made by means of a micrometer. |

|
REMOVAL
|
1. Turn out two fixing bolts and remove an anchor bracket of the brake mechanism.
|
2. Give wheel nuts, navernuty for disk fixing, and remove assembly of the last from a wheel nave. If the disk "became attached" and does not give in to removal, screw in carving between hairpins of fastening of a wheel of an opening pair of long bolts of the corresponding size and try to shift assembly by their gradual tightening. |
|
|
INSTALLATION
|
1. Accurately put on a disk a nave (try not to damage wheel hairpins). 2. Plant on the regular place an anchor bracket of the brake mechanism. Tighten bolts of fastening of a bracket with demanded effort. Establish brake shoes. 3. Establish a support and tighten with demanded effort bolts of its fastening. 4. Establish into place a wheel, lower the car on the earth and tighten wheel nuts with demanded effort (see. Specifications to Head of Control and routine maintenance). Several times squeeze out a brake pedal / cock the lever of the parking brake for the purpose of a usadka of blocks on a disk. If brake hoses were not disconnected, need for a prokachivaniye of hydraulic system is absent. Before starting car operation, make sure of serviceability of functioning of brakes. |
