Avalanche 1500 4WD V8-5.3L (2007)
Important:
^
DO NOT use any air tools to remove the guide pin bolts. Use hand tools only.
^
Install an open end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin
bolt. DO NOT allow the open end wrench to come in contact with the brake caliper. Allowing the open end wrench to come in contact with
the brake caliper will cause a pulsation when the brake are applied.
Using an open end wrench to hold the guide pin, loosen the guide pin bolt.
Notice: Support the brake caliper with heavy mechanic 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 guide pin bolt (1) from the brake caliper (2).
8. Rotate the brake caliper (2) upward until it stops on the caliper mounting bracket (5) and support the caliper with heavy mechanics wire or
equivalent.
