1. Prop up protivootkatny boots back wheels, then поддомкратьте a front of the car and establish it on props. Remove forward wheels.
2. Disconnect electroconducting from sensors of wear of blocks (see an illustration
the Scheme of connection of the sensor of wear of blocks and a cable of a drive of the parking brake). |
|
3. Disconnect a tip of a driving cable from the executive lever of the parking brake on assembly of the brake mechanism and liberate a cable cover from a support ledge (see also illustration
the Scheme of connection of the sensor of wear of blocks and a cable of a drive of the parking brake). Take the disconnected cable aside. |
|
|
4. By means of flat-nose pliers remove a small spring clip of fixing of a fixing finger, then take a finger from a support (see also illustration
of the Detail of installation of a finger of fastening of a support). In case of need use for finger knocking-out by a suitable drift. |
|
|
5. Liberate electroconducting of the sensor of wear of blocks from a clamp on the bottom party of a support. |
|
|
6. Lift a support up. Track, that the flexible brake hose did not appear will pull. |
|
|
7. Take blocks from an anchor bracket of the brake mechanism. Try to remember, how the ledge of an internal block in a piston groove settles down. |
|
|
8. Measure residual thickness of frictional overlays of both blocks. If though one of blocks is worn-out over an admissible limit (see. Specifications), it is necessary to make replacement of all blocks in both forward brake mechanisms. Blocks are subject to replacement also in case of detection of signs of a zamaslivaniye or non-uniform wear of slips. Previously it is necessary to reveal a source of leak and to eliminate the reason of its emergence. Prepare new brake shoes and a set of fixing fingers. |
|
|
9. If blocks are recognized suitable for further use, smooth out them a wire brush, special attention giving to purity of face walls and backs of metal substrates. Clean flutes in surfaces of frictional slips, having removed from them dirt and got stuck extraneous particles. Accurately clean pockets under installation of blocks in an anchor bracket of the brake mechanism. |
|
10. Before installation of new blocks check freedom of moving of a directing finger, also estimate a condition of its protective cover. With a brush remove from surfaces of the brake mechanism a brake dust (do not inhale it!). Check a condition of a protective boot of the piston. The piston examine on existence of signs of development of leaks and corrosion. In case of identification of any sort of suspicious defects address to section Removal materials, major maintenance and installation of supports of disk brake mechanisms of forward wheels. |
|
|
11. New blocks have big thickness, than removed from the car old in view of what for space release under from installation it is necessary to drown the piston in the cylinder. For a zaglubleniye of the piston it should be turned clockwise. For performance of this task the special firm Citroёn No. 9011-T adaptation is issued, however will approach and simply a piece of a metal core of suitable diameter. Drown the piston in the cylinder against the stop. |

|
|
Level the piston so that one of its grooves appeared opposite to a directing finger of a support. The label (and) over a groove (b) should settle down thus parallel to an axis of the gate of pumping. |
|
|
|
12. Establish brake shoes on the regular places (frictional slips to a disk). Track, that the directing ledge of an internal block entered into a reciprocal groove in a face surface of the piston. |
|
|
13. Lower a support in regular situation.
14. Fix electroconducting of the sensor of wear of blocks in a clip from the bottom party of a support, then connect the electric socket to the sensor.
15. Fill in a support a fixing finger so that the opening under installation of a spring clamp appeared from the party of the mechanism turned towards an internal block. Establish a clamp.
16. Get on the regular place on a support a driving cable of the parking brake, connect its tip to the executive lever. Check correctness of adjustment of a drive (see. The parking brake - general information and adjustments).
17. Repeat procedure for the brake mechanism of an opposite wheel.
18. Make sure of reliability of fixing of the car in the lifted situation, then start the engine and leave it working at single turns. Make sure that the lever the parking brake is released, then several times squeeze out a pedal of a foot brake for the purpose of activation of the mechanism of automatic correction of wear of blocks in supports. Release a pedal and make sure of reliability of fixing of wheels when raising the lever of the parking brake on 6 — 12 clicks of a ratchet. Muffle the engine. In case of need make adjustment of driving cables of the parking brake (see. The parking brake - general information and adjustments).
19. Once again make sure of serviceability of functioning of brake mechanisms and a drive of the parking brake, then establish to the place of a wheel, lower the car on the earth and tighten wheel bolts with demanded effort.
20. Check level of hydraulic liquid (address to Head Routine maintenance).
21. Remember that full efficiency of braking is reached only after extra earnings of new brake shoes. Try to avoid throughout the first 100 — 150 km of run of sharp braking. |
