Front Disc Brake Pads, Checking Thickness

Procedure

-- Visually inspect the outer and inner pads through the design-dependent rim openings to determine the thickness.

-- Remove the wheel bolt caps, if necessary. Refer to WHEEL BOLTS, TIGHTENING TO SPECIFICATION .

-- Mark the position of the wheel to the brake rotor.

-- Remove the wheel bolts and then the wheel.
