Rear Brake Disc Run-Out Check and Correction
REAR BRAKE DISC RUN-OUT CHECK AND CORRECTION
1. Remove the caliper support; then raise the caliper assembly upward and secure with a wire.
2. Check the disc surface for grooves, cracks and rust. Clean the disc thoroughly and remove all rust.
3. Place a dial gauge approximately 5 mm (0.2 inch) from the outer circumference of the brake disc, and measure the runout of the disc.
Limit: 0.08 mm (0.003 inch)
4. If the run-out of the brake disc is the limit value or more, change the phase of the disc and hub, and then measure the run-out again.
1. Before removing the brake disc, place a mating mark on both the wheel stud and disc with chalk where the runabout is greatest.
2. Place a dial gauge as shown in the illustration, and then move the hub in the axial direction and measure the play.
Standard value: 0 - 0.25 mm (0 - 0.010 inch)
3. If the play does not exceed the standard value install the brake disc at a different phase, and then check the runout of the brake disc again.
5. If the run-out cannot be corrected by changing the phase of the brake disc, replace the disc.
