Replacing the pads of the disc brake mechanisms of the front wheels
Replacing the pads of the disc brake mechanisms of the rear wheels
Wear assessment
1. Through the viewing windows in the brake calipers, assess the degree of wear of the brake pads - operating a car with pads worn below the permissible limit is fraught with damage to the rib between the sealing groove and the anther of the wheel cylinder piston.
2. Make sure there are no signs of fluid leaks developing, if necessary, check the system for leaks (see Section Checking the brake system for leaks).
3. Check for traces of leaks calipers (31a/31b), if necessary, replace them (see Section Removal and installation of a support).
Replacement
1. If equipped, disconnect the pad contact sensor connector (1) and remove the latter - defective sensors must be replaced.
2. Using a suitable drift (035) knock out the pins (41).
3. Remove the spring holder (41b).
4. If necessary, prying with a lever resting against the caliper body through a wooden spacer, remove the pads (43) from calipers (31a/31b).
5. Using a special clamp (031) press the piston of the wheel cylinder, if necessary, having previously pumped out a little brake fluid from the GTZ reservoir.
6. Clean the shoe guides, - do not use tools with sharp cutting edges to clean the guides.
7. Installation is carried out in the reverse order - pads equipped with gaskets (43b) should be lubricated with Cu-7439 before installation.
8. In conclusion, check the level of the brake fluid, if necessary, make the appropriate adjustment.
