Renewing brake disc with wheel bearing and ABS impulse ring on rear axle

Preparing

Vehicle for repair

Drive vehicle onto lifting platform
Deactivate electric parking brake
Remove rear wheels
Carry out a visual inspection

Before carrying out the repair, check all relevant components near the axle and wheel brake for damage, such as the tires, transverse control arms and brake hoses !

Removal

Removing the brake discs

Remove retaining spring (1) from brake caliper
Remove protective plugs (2) from guide bolts
Inspect protective plugs and damping sleeves (3) for damage
Undo and remove guide bolts (4)
Remove brake caliper (5) from brake anchor plate (6) and hang on spring using a suitable hook.

Avoid twisting the brake hose when doing this.

Remove brake pads
Slacken and unscrew the fixing screws on the caliper anchor bracket
Remove brake caliper anchor bracket
Remove wheel hub cap
Slacken and unscrew hub nut
Remove brake disc with wheel hub

Note: To avoid damage, do not leave the brake caliper hanging from the brake hose!

Cleaning and inspection

Clean the following components and inspect them for damage prior to assembly:

Brake caliper anchor bracket

Carefully remove any corrosion from the brake pad contact faces using a wire brush

Brake caliper

§ Check the dust protection boot of the piston for damage

§ Clean guide bolts and check for damage

§ After cleaning, apply a thin coat of silicone-based grease to the sliding surfaces

ABS-Sensor

Check for correct seating and for signs of damage

Axle journal

The axle journal should be free of burr, flat and rust-free
After cleaning, coat the axle journal with a little calibrating oil and spread evenly using a clean cloth

Only clean using brake cleaner, a brush and a lint-free cloth. It is essential to avoid mechanical damage to the guide surfaces.

Preparations

Preparing for installation:

Compare new and old brake discs.
Check the ABS impulse ring (magnetic coder) installed on the brake disc prior to installation
Clean brake disc with brake cleaner if necessary
Check level of brake fluid in expansion tank
If at the MAX. mark, unscrew cover from brake fluid tank and extract a little fluid

Installation

Installing the brake disc:

Position the brake disc with integrated wheel bearing centrally on the axle journal and slide on
Screw on hub nut and tighten to specified tightening torque
Fit hub cap
Install brake caliper anchor bracket
- Tighten fixing screws to specified torque

Push brake piston right back using reset tool
- At the same time, turn the piston to the right
- Please note the brake fluid level in the expansion tank

Insert the piston-side inner brake pad

When doing so, make sure that all three brackets of the retaining spring are inserted into the piston groove

Fit external brake pad
Position and mount brake caliper
Screw in guide bolt and tighten to specified torque
- Clean the sliding surfaces of the bolts and apply a thin coat of silicone-based grease
Place dust covers onto the damping sleeves
Insert brake caliper retaining spring

Check clamping force of retaining spring and replace if necessary

Hook in hand-brake cables
- Ensure that the cables are correctly positioned and engaged

Depress the brake pedal several times to move the brake pads to the required working position
Check the brake fluid level in the expansion tank and fill up to the "MAX" mark if necessary
- Replace brake fluid if necessary

Actuate parking brake several times (pull up, release)
When the parking brake is released and the lever is pulled up again, there must be play or a clearance of 1 to 2 mm at the end of the cable by the brake caliper.

Carry out final check with diagnostic unit
- Read out fault memory and clear if necessary

Before mounting the wheel, clean the contact faces of the rims

Carry out a functional check on the test stand and take a test drive
- Run in brake discs and brake pads
- Comply with the run-in instructions from the brake pad and vehicle manufacturers
