Caution: Refer to Brake Dust Caution in Service Precautions.
Removal Procedure
1. Raise and support the vehicle. .
2. Remove the tire and wheel assembly.
3. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.
4. Tighten the C-clamp until the caliper piston is compressed into the caliper bore enough to allow the caliper to slide past the brake rotor.
5. Remove the C-clamp.
Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's 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.
Important: Do NOT disconnect the hydraulic brake flexible hose from the caliper.
6. Remove the brake caliper and the caliper mounting bracket as an assembly from the steering knuckle and support the assembly with heavy
mechanic's wire, or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose.
7. Matchmark the position of the brake rotor to the wheel studs.
8. Remove the brake rotor.
Installation Procedure
Important: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should 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,
