Rear Disc Brake Pads, Checking Thickness

NOTE:

Due to the geometry of the rims on some vehicles, an assessment or measurement of the remaining pad thickness may be hindered. Should this be the case, move the wheel to the side where the brake pad wear indicator is installed to better assess or measure the remaining pad thickness.

Procedure

-- Shine a flashlight through an opening in the wheel rim.

-- Check the thickness of outer pad visually.

-- Shine a flashlight on the inner pad and hold up a mirror.

-- Check thickness of inner pad visually.

a - Inner and Outer Pad Thickness "without" Backing Plate

Permissible wear: 2 mm

NOTE:

With a pad thickness (without backing plate) of 2 mm, the brake pads have reached their wear limit and must be replaced (repair procedure).

If the disc brake pads are replaced, the brake rotors must also be checked for wear. Checking and replacing the brake pads, if necessary, is a repair procedure.

Procedure

-- Check the brake rotor for wear. Refer to OVERVIEW - REAR BRAKES .

-- If necessary, secure the wheel at the marked position.

-- Tighten the wheel bolts diagonally to the tightening specification. Refer to WHEEL BOLTS, TIGHTENING TO SPECIFICATION .

-- After the procedures have been completed, return the adapter to the vehicle tool kit.

-- Pull off wheel bolt caps, if necessary.
