Brake Pads, Removing And Installing, TTRS And Ceramic Brakes: Installing

WARNING: This page is about a different variant/trim than selected.
NOTE:

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

NOTE:

Use the complete repair kit when installing new brake pads.

Always replace brake pads on both sides of the axle.

CAUTION:

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.
NOTE:

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.

WARNING:

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.

NOTE:

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.

-- Insert the brake pads -4 and 7- into the brake caliper.

-- 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.

NOTE:

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-.

CAUTION:

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 .

WARNING:

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.
