Rear Brake Pads, Removing And Installing: Installing
Clean bolts before reusing.
Replacing the damaged bolts. Refer to the Parts Information.
Always replace the self-locking bolts. Refer to the Parts Information.
Install in reverse order of removal and note the following:
-- If the brake pads are being replaced, check the brake rotors for wear and damage.
Always replace brake pads on the same axle at the same time.
When installing new brake pads use the repair kit and wire for the new brake pad wear indicator sensor.
Replace the brake caliper bolts after removing.
There is a health risk.
- Do not blow out brake system with compressed air.
Use only mineral spirits to clean the brake caliper.
Check the brake caliper piston protective caps for damage and install the complete repair kit, if necessary.
There is a risk of contamination and paint damage from escaping brake fluid.
- If the brake pads are worn out and unnecessary brake fluid was filled, the brake fluid may overflow, when the brake caliper pistons in the brake cylinders are pressed back.
- Check the brake fluid level before pressing back the brake caliper pistons. If there is brake fluid up to the "MAX" mark, some brake fluid will need to be extracted.
- Use the :VAS5234 to extract brake fluid from the brake fluid reservoir.
-- Use the :T10145 to completely press back the brake caliper piston.
-- Clean the brake carrier on the retaining clip contact surfaces and thinly coat them with lithium grease.
-- If reusing, install the marked brake pads in the same location.
-- Insert brake pads in brake carrier.
Make sure the brake pads are installed at the correct location.
The brake pad clips -A- must sit correctly in the contact surfaces in the brake carrier.

-- Push the brake caliper over the installed brake pads.
Make sure that the wire and brake hose are routed correctly.
Make sure the brake hose is not blocked, bent, twisted or rubbing against the vehicle.
Clean bolts before reusing.
Replacing the damaged bolts. Refer to the Parts Information.
Always replace the self-locking bolts. Refer to the Parts Information.
-- Tighten the brake caliper bolts -arrows- -item- 3 by counterholding at the guide pins -1 and 2-.
Check the contact for the brake pad wear indicator sensor for damage, replacing if necessary.
Make sure that the brake pad wear sensor fits correctly in the brake pad.
If the clips go missing, the wire for the brake pad wear indicator sensor must be replaced.
Insert the contact -4- for the brake pad wear indicator sensor with the clip -3- until it engages in the inner brake pad.
-- Secure the sensor for the brake pad wear indicator sensor with the protective cap -2- and the clip -1-.
-- With the vehicle stationary, firmly press the brake pedal several times so that the brake pads in the operating condition properly sit in their respective position.
-- Drive the parking brake motors up using the Vehicle Diagnostic Tester by following the instructions in the display.
Risk of accident!
- With the vehicle stationary, firmly press the brake pedal several times so that the brake pads in the operating condition properly sit in their respective position.
- Make sure the brakes are working correctly before driving the vehicle for the first time.
