Brake Rotor Replacement-Front

Removal Procedure
The brake rotor can be removed without separating the caliper from the caliper bracket (JC1 System).

Important: Do not disconnect the brake hose from the caliper.





1. Remove the brake caliper. Refer to Brake Caliper Replacement - Front (Single Piston) or Brake Caliper Replacement - Front (Dual Piston).

Notice: Do not allow the brake components to hang from the flexible brake hoses. Damage to the brake hoses could result.

2. Suspend the caliper with a wire.
3. Remove the brake pads (JC1 System). Refer to Brake Pads Replacement - Front (Single Piston Caliper) or Brake Pads Replacement - Front (Dual Piston Caliper).
4. Remove the caliper bracket. Refer to Brake Caliper Bracket Replacement.
5. Remove and dispose of the sheet metal retainers (UC1 System).
6. Remove the wheel bearings (JM3 System). Refer to Wheel Hub, Bearing, and Seal Replacement (RWD Pickup) or Wheel Hub, Bearing, and Seal Replacement (4WD Pickup and Utilities) in Steering and Suspension.
7. Remove the rotor (1).
8. Inspect and clean all the parts. Replace parts as necessary.
9. Refinish the rotor if necessary. Refer to Brake Motor Refinishing.

Installation Procedure

^ Tools Required
- J 42450-A Hub Cleaning Kit

Notice: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the rotor and flange with the J 42450 hub cleaning kit. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.





1. Use the J 42450-A to clean the hub flange (JC1 System).
2. Install the wheel bearings (JM3 System). Refer to Wheel Hub, Bearing, and Sea/ Replacement (RWD Pickup) or Wheel Hub, Bearing, and Seal Replacement (4WD Pickup and Utilities) in Steering and Suspension.





3. Install the rotor (1).
4. Install the caliper bracket. Refer to Brake Caliper Bracket Replacement.
5. Install the brake pads (JC1 System). Refer to Brake Pads Replacement - Front (Single Piston Caliper) or Brake Pads Replacement - Front (Dual Piston Caliper).
6. Install the caliper. Refer to Brake Caliper Replacement ->Front (Single Piston) or Brake Caliper Replacement - Front (Dual Piston).
