INSPECTION
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 value : 26.0 mm(1.024 in.)
Limit : 24.4 mm(0.961 in.)
2. Thickness variation should not exceed 0.005 mm (0.0004 in.) (circumference) and 0.01 mm ( in.)(radius) at any directions.
3. If wear exceeds the limit, replace the discs and pad assembly left and right of the vehicle.
Front Brake Disc Run Out Check
INSPECTION
FRONT BRAKE DISC RUN OUT CHECK
1. Place a dial gauge about 5mm (0.2 in.) from the outer circumference of the brake disc, and measure the run out of the disc.
Brake disc run out
Limit : 0.1 mm (0.004 in.) or less
Extremely tight specification : 0.04 mm (0.0016 in.)
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.
