).
3. Remove the brake caliper bracket bolts (1).
Caution: Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible
brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which
may cause damage to the brake hose and in turn may cause a brake fluid leak.
4. Remove the brake caliper and bracket assembly and support with heavy mechanics wire or equivalent.
5. Remove and discard the brake rotor retainers (1), if equipped.
6. If installing the original brake rotor, mark the position of the rotor to the wheel hub.
7. Remove the brake rotor (2).
Installation Procedure
Note: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants must be cleaned from the hub/axle flange and the
brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake
pulsation.
1. Using the J 42450-A , thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
2. Using the J 41013 , thoroughly clean any rust or corrosion from the mating surface of the brake rotor.
3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure there are no foreign particles or debris remaining.
