1999 GMC Forward Control 5.7 R, AutomaticSECTION Removal Procedure
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the tire and wheel assembly. Tire and Wheel Removal and Installation in Tires and Wheels.
  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. Using the C-clamp, compress the piston into the caliper bore just enough to allow the caliper to slide away from the rotor.
  5. Remove the C-clamp.
  6. NOTE: Support the brake caliper with heavy mechanic's 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.
  7. Remove the caliper bracket bolts. Do not disconnect the brake flexible hose bolt.

    Remove the brake caliper and the caliper mounting bracket as an assembly from the suspension knuckle and support the assembly with heavy mechanic's wire, or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose. Refer to Brake Caliper Bracket Replacement - FrontΒ .
