Withdrawal
1. Set the car to the parking brake.
2. Install support bars under the rear wheels.
3. Loosen the front wheel bolts.
4. Raise and support the front of the vehicle.
5. Remove wheel.
6. Unscrew the fastening nut, disconnect the brake hoses and plug the hole in the brake hose remaining on the car.
7. Loosen the two guide pins (see fig. Teves brake caliper), having previously removed the dirt-proof caps, and remove the bracket body.
Disassembly
1. Remove protective cover (see fig. Teves brake caliper) piston. Clamp the clamp body in a vice with soft metal jaws. Remove the piston from the cylinder by supplying compressed air through the brake hose fitting and holding the piston by hand or by placing a piece of wood on it.
2. Remove the O-ring from the cylinder using a wooden spatula. The use of metal objects is not recommended, as this can damage the cylinder groove under the sealing ring.
3. Unscrew the bleed valve.
4. Flush the piston and cylinder with fresh brake fluid.
Inspection and Troubleshooting of Clamp Body Parts
1. Inspect the working surface of the piston and cylinder. If there are signs of wear, corrosion, cavities and nicks on the working surfaces of the piston and cylinder, replace the bracket body complete with the piston.
2. The sealing ring and the protective cap of the piston must be replaced.
Assembly
1. Lubricate the inside of the cylinder with fresh brake fluid.
2. Lubricate the new O-ring with fresh brake fluid and insert into the cylinder bore.
3. Lubricate the new protective cover with fresh brake fluid and insert it into the groove on the piston.
4. Insert the piston into the cylinder with the force of your fingers, without using any tools, and using a screwdriver, carefully insert the outer edge of the protective cover into the groove of the cylinder.
5. Lubricate the bleed valve with fresh brake fluid and screw it into the caliper body.
Installation
The bracket body is installed in the reverse order of removal. At the same time, tighten the two guide pins to a torque of 25 Nm (2.5 kgf·m), while holding the guide pin with the wrench. After installation, bleed the repaired brake (cm. subsection 10.15).
