CAUTION: The brake disc (1126) runout specification must be met to ensure correct brake
performance without roughness complaints.
CAUTION: Do not install brake discs that are less than the minimum thickness specified.
Do not machine a brake disc below the minimum thickness specification.
NOTE: When installing brake discs, always align the painted match marks on the brake discs with
those on the front hub or rear axle.
NOTE: When installing brake discs, always apply anti-seize lubricant to the brake disc-to-front hub or
to the brake disc-to-rear axle mating surfaces.
1. Do not remove the tire and wheel assembly. Tighten the wheel nuts to specification with a
torque stick or torque wrench.
2. Raise and support the vehicle.
3. Assemble the Brake Measurement Kit, using the spherical tip extension.
4. Locate an opening on the inboard side of the dust shield that will allow the dial indicator tip to be
positioned at least 5 mm (0.2 inch) from the outer edge of the brake disc.
5. NOTE: Do not clamp the gauge set to a vehicle component separated from the brake disc by a
flexible joint, such as a ball joint or body mount.
Clamp the Brake Measurement Kit on the vehicle, making sure the flexible indicator arm and
probe tip do not touch the dust shield or tire while rotating.
6. NOTE: For rear wheel measurement only, have an assistant push in on the wheel cover or axle
shaft center while rotating the wheel.
Rotate the wheel for six revolutions, and record the total indicated runout.
