Brake Discs
CAUTION:
Using an impact tool without a torque socket leads to unevenly tightened lug nuts. This causes brake disc on-vehicle lateral runout and brake roughness.
NOTE:
It is generally not necessary to install new brake discs to address brake noise concerns.
- Remove the brake disc. For front disc brakes, refer to FRONT DISC BRAKE or REAR DISC BRAKE .
- Inspect the brake disc and measure the brake disc thickness in a minimum of 4 places around the circumference of the brake disc. Record the measurements.
- Install new brake discs if any thickness measurement is less than the minimum specification. For front disc brakes, refer to FRONT DISC BRAKE or REAR DISC BRAKE .
- Install new brake discs if cracked. For front disc brakes, refer to FRONT DISC BRAKE or REAR DISC BRAKE .
- Machine the brake discs if the diagnosis has revealed vibration in the steering wheel, seat, or pedal while braking. Heavily scored brake discs, similar to that caused by pads worn down to the backing plate, should also be machined. In order to machine, the thickness of the discs must be greater than the minimum thickness to machine specification. For front disc brakes, refer to FRONT DISC BRAKE or REAR DISC BRAKE .
