Disc Brake System: Testing and Inspection

BRAKE: FRONT BRAKE: INSPECTION

INSPECTION

1. INSPECT BRAKE CYLINDER AND PISTON
(a) Check that the side of the front disc brake piston and the inside of the cylinder are not damaged.
If necessary, replace the front disc brake cylinder and front disc brake piston.
2. INSPECT PAD LINING THICKNESS





(a) Using a ruler, measure the pad lining thickness.
Standard thickness:
11.0 mm (0.433 in.)
Minimum thickness:
1.0 mm (0.039 in.)
HINT: If the disc brake pad thickness is at the minimum or less, replace the disc brake pad.

3. INSPECT NO. 1 FRONT DISC BRAKE PAD SUPPORT PLATE
(a) Clean the area where the No. 1 front disc brake support plate contacts the brake pad using brake cleaner. Check that there are no deformations, cracks or rust.
(b) Check that there is no looseness or deformation with the front disc brake cylinder mounting installed.
(c) Make sure that the support has sufficient rebound when installing the pad. Check that the pad does not easily drop after installation.
4. INSPECT NO. 2 FRONT DISC BRAKE PAD SUPPORT PLATE
HINT: Check the No. 2 pad support plate using the same inspection procedures for the No. 1 pad support plate.

5. INSPECT DISC THICKNESS





(a) Using a micrometer, measure the disc thickness.
Standard thickness:
22.0 mm (0.866 in.)
Minimum thickness:
20.0 mm (0.787 in.)
HINT: If the disc plate thickness is at the minimum or less, replace the front disc.
