FRONT DISC BRAKEINSPECTION
FRONT BRAKE DISC THICKNESS CHECK
1. Remove all rust and contamination from the surface, and measure the disc thickness at 8 points, at least, of same distance (5 mm) front the brake disc outer circle.
Front brake disc thickness
Standard valve: 26.0 mm (1.024 inch)
Limit: 24.4 mm (0.961 inch)
2. Thickness variation should not exceed 0.005 mm (0.0002 inch) (circumference) and 0.01 mm (inch) (radius) at any directions.
3. If wear exceeds the limit, replace the disc and pad assembly left and right of the vehicle.
FRONT BRAKE PAD CHECK
1. Check the pad wear Measure the pad thickness and replace it, if it is less than the specified value.
Pad thickness
Standard value: 11 mm (0.433 inch)
Service limit: 2.0 mm (0.0787 inch)
2. Check that grease is applied, and the pad and backing metal for damage.
FRONT BRAKE DISC RUN OUT CHECK
1. Place a dial gauge about 5 mm (0.2 inch) from the outer circumference of the brake disc, and measure the run out of the disc.
Brake disc run out
Limit: 0.03 mm (0.0012 inch) or less
2. If the run out of the brake disc exceeds the limit specification, replace the disc, and then measure the run out again.
3. If the run out does not exceed the limit specification, install the brake disc after turning it 180° and then check the run out of the brake disc again.
4. If the run out cannot be corrected by changing the position of the brake disc, replace the brake disc.
