GTO V8-6.0L VIN U (2005)
7. Use a wrench in order to prevent the lower guide pin (10) from turning.
8. Remove and discard the lower guide pin bolt (7).
9. Notice: 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.
Important: Do NOT disconnect the hydraulic brake flexible hose from the caliper.
Rotate the caliper assembly up and support the caliper with heavy mechanic's wire, or equivalent. Verify there is no tension on the brake hose.
10. Remove the 2 brake pads (13,14).
Inspection Procedure
1. Inspect the brake pads for wear. If the pad thickness is less than the specification, replace the brake pads in axle sets.
2. Inspect the disc brake hardware. Replace the components if necessary.
3. Inspect the caliper. Repair or replace the components as necessary.
4. Important: Refinish or replace the rotor ONLY if the condition of the rotor requires service. DO NOT refinish the rotor if the brake pads are the
only components requiring service.
Measure the brake rotor thickness. Refinish or replace the rotor as necessary.
5. Measure the brake rotor thickness variation. Refinish or replace the rotor as necessary.
6. Inspect the surface of the brake rotor. Refinish or replace the rotor as necessary. Refer to Brake Rotor Surface and Wear Inspection.
7. Measure the brake rotor assembled lateral runout. Refinish or replace the rotor as necessary.
Installation Procedure
1. Clean the surface of the piston which contacts the inner brake pad.
2. Clean the surface of the caliper which contacts the outer brake pad.
3. If the caliper piston is not compressed into the caliper bore, complete the following steps:
1. Place an old brake pad (2) or a block of wood against the caliper piston.
2. Install a large C-clamp over the body of the brake caliper. Position 1 end of the clamp against the caliper body adjacent to the brake hose
fitting. Position the other end of the clamp against the old brake pad or the wood.
3. Tighten the clamp in order to compress the caliper piston into the caliper bore.
