Brake Discs
CAUTION:
- Using an impact tool without a torque socket will lead to unevenly tightened lug nuts. This causes brake disc on-vehicle lateral runout and brake roughness.
NOTE:
- It is generally not required to install new brake discs to address noise issues.
- Remove the brake disc. See BRAKE DISC , .
- Inspect the brake discs 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. See BRAKE DISC , .
- Install new brake discs if cracked. See BRAKE DISC , .
- 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, discs must be above the minimum thickness to machine specification. See BRAKE SPECIFICATIONS . See BRAKE DISC MACHINING EBW0410AB .
