Disc Brake Rotor (B 2-10, front B 2-00 optional)
NOTE: The front brake rotor is an integral part of the front hub. If the brake
rotor is worn beyond its service limits, then the front hub must be
replaced. Refer to
Front Axle Service
for information on replacing
the front hub.
NOTE: Depending on the rear axle configuration, the rear brake rotor may
be an integral part of the rear axle. If the brake rotor is worn beyond
its service limits, then the rear axle must be replaced. Refer to
Transmission
section for information regarding replacing the rear
axle
NOTE: The wheel must be removed to accurately measure the rotor
thickness. Refer to
Tires and Wheels
section for information on
removing the wheel.
1. Measure the run out of the rotor at its maximum
diameter. If the run out exceeds 0.005, then the
rotor must be machined. Do not machine the rotor
beyond its service limits.
NOTE: A bent axle or damaged rear axle could
cause excessive brake rotor run out.
Rotor removed for clarity. The rotor does not
have to be removed for this procedure.
Do not use a rotor that is
worn beyond its service
limits. A rotor worn beyond
its service limits could fail
and cause loss of brakes
resulting in severe bodily
injury and/or property
damage.
2. Measure the thickness of the brake rotor in 3 places.
If the brake rotor thickness is less than 0.20-inches,
then the rotor must be replaced.

brakes are asbestos free. However, there is
the possibility that the original brakes were replaced with aftermarket
parts containing asbestos. Since this possibility exists, all brake parts
should be handled as if they contain asbestos. Refer to appendix C
for recommended handling precautions.
