Disc Brake System: Testing and Inspection

FRONT BRAKE

INSPECTION
1. CHECK BRAKE CYLINDER AND PISTON
a) Check the cylinder bore and piston for rust or scoring.
If necessary, replace the cylinder and piston.





2. CHECK PAD LINING THICKNESS
a) Using a ruler, measure the pad lining thickness.
Standard thickness: 11.0 mm (0.433 inch)
Minimum thickness: 1.0 mm (0.039 inch)
If the pad lining thickness is equal to or less than the minimum, replace the pad.
3. CHECK FRONT DISC BRAKE PAD SUPPORT PLATE
a) Check the 2 support plates.

HINT: Make sure that the support plates have sufficient rebound and are free from deformation, cracks, wear, rust and dirt. If necessary, replace the support plates.





4. CHECK DISC THICKNESS
a) Using a micrometer, measure the disc thickness.
Standard thickness: 22.0 mm (0.866 inch)
Minimum thickness: 20.0 mm (0.787 inch)
If the disc thickness is less than the minimum, replace the disc.
