Disc Calipers & Pads - DELCO Floating Caliper: Removal

  1. Remove 2/3 of brake fluid from front reservoir in master cylinder. Raise vehicle and support with safety stands. Remove wheel assembly. Place a large "C" clamp on caliper so that solid side of clamp rests against metal part of outer disc pad.
  2. Tighten "C" clamp until caliper moves away from vehicle far enough to push piston to bottom of bore. Remove "C" clamp. Do not disconnect brake line to caliper. Remove 2 mounting bolts which retain caliper to support bracket.
  3. Lift caliper off rotor and remove inner disc pad. Pry out outer disc pad. Place caliper on front suspension arm so that caliper weight is not supported by brake hose.
