Brake Pads, Removing And Installing, TTRS And Ceramic Brakes: Installing
Clean bolts before reusing.
Replace damaged bolts.
Always replace self-locking bolts.
Install in reverse order of removal and note the following:
If the brake pads are being replaced with new pads, check the brake rotors for wear and damage.
-- Check the wear specification of the brake rotors. Refer to BRAKES TECHNICAL DATA, FRONT BRAKES .
Refer to CERAMIC BRAKE ROTOR, DETERMINING WEAR
Use the complete repair kit when installing new brake pads.
Always replace brake pads on both sides of the axle.
There is a risk of contamination and paint damage from escaping brake fluid.
- If the brake pads are worn out and brake fluid is filled unnecessary, the brake fluid may overflow, causing the pistons in the brake cylinders to be pressed back.
- Check the brake fluid level before pressing back the pistons. If there is brake fluid up to the "MAX" mark, some brake fluid will need to be extracted.
- Use the Brake Charger/Bleeder Unit :VAS5234 to extract brake fluid from the brake fluid reservoir.
Use only mineral spirits to clean the brake caliper.
Check the brake piston protective caps for damage and install the complete repair kit, if necessary.
There is a health risk.
- Do not blow out brake system with compressed air.
-- Use the :T10145 to press the brake piston all the way back into the brake caliper.
Coat the brake pad plates with grease.
Coat the guide pin with lithium grease.
-- Clean the brake caliper on the contact surfaces -1, 2 and 3- to the brake pads and the retaining pins -arrows- and thinly coat them with lithium grease.
-- On used brake pads check the wire -arrow- for the brake pad wear sensor on the brake caliper for damage.
Coat the brake pad plates with grease.
Coat the guide pin with lithium grease.
-- Insert the brake pads -4 and 7- into the brake caliper.
- The brake pad with brake pad wear sensor is located on the bottom and faces toward the inside of the vehicle.
-- Press the brake pad springs -1 and 5- down one after the other and drive the brake pad pins -2 and 6- all the way into the brake caliper.
When driving in the brake pad pins, make sure that the brake caliper coating is not damaged.
-- Connect the connector -1- on the right brake caliper and secure the wire for the brake pad wear sensor with the dust cap -2-.
If brake pads are ceramics, wheel must not fall on brake rotor, otherwise it will be irreparably damaged. To install/remove wheel, install two assembly pins from vehicle tool kit in mounts on wheel bolts. The long assembly pin is in the upper position.
-- Install the front wheel. Refer to Wheels and Tires .
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.
-- Check brake fluid level, and fill if necessary.
