Removal Procedure

    CAUTION:: If one stud is damaged, replace all the studs. A loose-running wheel may cause only one stud to break, but the other studs could have internal fatigue. Replacing only the broken stud and remounting the wheel may cause further damage and personal injury. If the stud holes in the wheels have become enlarged or distorted, replace the wheel.

  1. Siphon brake fluid from the master cylinder.
  2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  3. Remove the tire and wheel assembly from the vehicle. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  4. Compress the brake caliper piston with a C-clamp.
  5. Remove the 2 brake caliper mounting bolts.
  6. Notice: Do not allow the brake components to hang from the flexible brake hoses. Damage to the brake hoses could result.

  7. Remove the caliper from the rotor. Suspend the caliper assembly with wire in order to prevent damage to the brake hose.
  8. Remove the brake rotor. Refer to Brake Rotor Replacement in Disc Brakes.
  9. Install 2 wheel nuts onto 2 wheel studs.
  10. Use a pry bar on the 2 nuts in order to prevent the hub from turning.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
