Contents: Removal ↓ Installation ↓
Note: Removing and installing the brake pads of the rear disc brake is basically the same as for the front disc brake. Therefore, you should also read the chapter "Removal and installation front brake pads". Strictly follow all general instructions and safety instructions given in this chapter.
This chapter only provides the distinguishing features for removing and installing brake pads for the rear disc brake.
Removal
Caution: If the brake pads are to be reinstalled, their location must be marked before removal. Changing the pads around, for example, swapping the outer pad with the inner pad or moving the pad from the right wheel to the left wheel and vice versa, is not allowed. Changing the location of the pads may result in uneven braking action. It is recommended to use only original brake pads approved for use by the vehicle manufacturer. It is imperative to replace all the brake pads on the axle at the same time, even if only one of them has reached the wear limit.
For vehicles with a brake pad wear sensor, disconnect the sensor plug connector, see the relevant chapter for the front disc brake.
Release the handbrake lever. Using a screwdriver, press the locking bracket "1" and remove it with a downward movement.
Press the brake lever "2" in the direction of the arrow and unfasten the handbrake cable "3". Remove the handbrake cable from the holder on the brake caliper.
Remove the upper and lower brake caliper mounting bolts "15" while holding the corresponding guide pins, see figure S46-0097.
Remove the caliper body and hang it on a wire to the body or a coil spring.
Caution: The brake hose must not be stretched or twisted.
Remove the brake pads and the arrow springs holding them.
Measure the thickness of the brake disc, see the relevant chapter.
Clean the brake caliper.
Caution: Do not use any wire brushes to clean the housing. Clean the brake caliper only with alcohol.
Installation
Using the special tool VW-3272 or HAZET 4970/6, press the piston into the brake caliper cylinder.
Caution: Do not push the piston back with a normal return tool as this will destroy the handbrake adjustment mechanism.
Using a special tool, slowly screw in the piston under strong pressure, turning it to the right (clockwise). The tool shoulder - left arrow - should rest on the brake caliper. If the piston stroke is heavy, turn it with a 13 mm wrench by the chamfers "A" on the tool spindle.
Remove the protective film from the back of the brake pads.
Insert the retaining springs "arrows" and brake shoes into the brake shoe guide.
Note: The repair kit contains 4 self-locking bolts.
These bolts must be used every time.
While holding the guide pins, screw the brake caliper to the brake shoe guide using new self-locking bolts. Tighten the mounting bolts to a torque of 35 Nm.
Press the brake lever down and attach the handbrake cable to it.
Secure the handbrake cable to the counter support with a locking bracket.
Adjust the handbrake, see the relevant chapter.
Press the brake pedal hard several times with the vehicle stationary, check the brake fluid level in the expansion tank.
