CAUTION
This keeps the coil spring compressed. Use care to support the control arm adequately, or personal injury could result.

  1. Remove the disc brake caliper. See . Secure the caliper to the suspension using wire. Do not allow the caliper to hang by the brake hose. Insert a piece of wood between the shoes to hold the piston in the caliper bore. (The block of wood should be about the same thickness as the brake disc.).
  2.  


CAUTION
Some brake pads contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
