Install in reverse order of removal and note the following:

-- When the brake pads are replaced, check the brake rotors for wear and damage:

Brake rotor wear limit. Refer to TECHNICAL DATA, BRAKES .

NOTE:

Always replace brake pads on both sides of the axle.

Use the complete repair kit when installing new brake pads.

WARNING:

Health Risk.

Do not blow out brake system with compressed air.

NOTE:

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. Refer to BRAKE CALIPER PISTON, REMOVING AND INSTALLING, 1LA/1LJ .

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.

-- Use the :T10145 to press the brake caliper piston completely back into the brake caliper.
