INSPECTION
1. INSPECT BRAKE CYLINDER AND PISTON
(a) Check the brake cylinder bore and the brake piston for rust or scoring.
2. INSPECT PAD LINING THICKNESS
(a) Using a ruler, measure the pad lining thickness.
Standard thickness: 12.7 mm (0.500 inch)
Minimum thickness: 1.0 mm (0.039 inch)
3. INSPECT FRONT DISC BRAKE PAD SUPPORT PLATE
(a) Inspect the front disc brake pad support plate (No. 1) and the front disc brake pad support plate (No. 2).
(1) Make sure that it has sufficient rebound, no deformation cracks or wear, and all rust, dirt are cleaned off.
HINT: If necessary, replace the brake pad support plate.
4. INSPECT DISC THICKNESS
(a) Using a micrometer, measure the disc thickness.
Standard thickness: 28.0 mm (1.102 inch)
Minimum thickness: 26.0 mm (1.024 inch)
