Replacement колодок forward brake mechanisms

Колодки disk brakes it is necessary to change on both forward wheels simultaneously - replacement колодок only on one wheel will lead to unequal braking. The dust formed at deterioration колодок, can contain asbestos, unhealthy. Never blow off its compressed air and try not to inhale. Do not use for clearing of components of brakes mineral solvents. Apply only a special cleaner or methyl spirit.

At installation use a new bolt of a directing pin of a support.


1. Cock a manual brake, then поддомкратьте a forward part of the car and reliably establish it on axial props. Remove forward wheels.

2. Track conducting of the gauge of deterioration колодок to a socket and disconnect it (address to an accompanying illustration). Remember a correct arrangement of electroconducting and let out it from fixing скоб.

3. Deduce a support outside. It will push the piston into the cylinder and will facilitate removal and installation колодок.

4. Turn away a bolt of the bottom directing pin of a support, using a suitable wrench and having blocked a pin the second key. Will throw out a bolt - it is subject to replacement (address to illustrations).

5. Turn a support to take away it from колодок, and tie up a wire to a suspension bracket rack (address to an accompanying illustration). Do not allow a support to hang on a hose.

6. Take brake Pads from an arm (address to illustrations).

7. Measure a thickness of everyone brake Pads (a metal basis plus an overlay) (address to an accompanying illustration). If any from колодок it is worn out till the minimum thickness specified in Specifications, all four Pads should be replaced. Колодки also are subject to replacement, if at least one of them is polluted by oil or greasing as to clear it it is impossible. If unequal deterioration or pollution is found out, find and eliminate the reason before installation new колодок.

8. If brake Pads are serviceable, accurately clear their soft wire brush, giving particular attention to lateral sites and an underside of a metal basis. Clear also an internal surface of a fixing arm of a support.

9. Before installation колодок be convinced that directing pins freely slide in an arm and that rubber covers of directing pins are not damaged (address to an accompanying illustration). Clean off a dust from a support and the piston a brush. Examine a dustproof cover of the piston and the piston on presence of damages, smudges and corrosion. Servicing of these components is described in Section Removal, a partition and installation of supports of forward brake mechanisms.

10. If are established new Pads, it is necessary to push the support piston into the cylinder that for them the place was formed. Use for this purpose a clamp or a flat screw-driver. Consider that thus liquid level in the tank will raise (it is recommended to pump out preliminary from it a liquid part).
11. Establish Pads into position, remembering that internal колодка is equipped by the deterioration gauge.

12. Develop a support into position. Be convinced that springs колодок are established correctly, then press a support and establish a new bolt of a directing pin (address to an accompanying illustration). Tighten a bolt the effort resulted in Specifications.

13. Connect a socket of conducting of the gauge of deterioration brake Pads and fix wires скобами.
14. Press a brake pedal some times to move Pads closely to a disk.
15. Repeat the procedure described above on the second support of a forward brake.
16. Establish wheels, then lower the car on the earth and tighten wheel bolts the effort resulted in Specifications.
17. Check up level of a brake liquid as it is described in Section the routine maintenance Schedule.
