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

Install in reverse order of removal and note the following:

NOTE:

Clean the bolts and nuts before reusing.

Always replace self-locking nuts and bolts.

Always replace damaged nuts and bolts.

-- If the brake pads are being replaced, check the brake rotors for wear. Refer to appropriate service information.

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 :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 entire repair kit, if necessary. Refer to BRAKE CALIPER PISTON, REMOVING AND INSTALLING, EIGHT-PISTON BRAKE .
