Brake Pads - Front Single Piston Caliper: Removal

  1. Inspect the fluid level in the brake master cylinder reservoir.
  2. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
  3. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
  4. Raise and support the vehicle.
  5. Remove the tire and wheel assembly.
  6. Install and hand tighten a wheel lug nut to hold the brake rotor in place.
  7. Compress the front caliper piston. Install a large C-clamp over the top of the brake caliper housing and against the back of the outboard pad. Slowly tighten the C-clamp until the piston is fully seated in the caliper bore. Remove the C-clamp from the brake caliper.
  8. Remove the brake caliper assembly from the mounting bracket. See BRAKE CALIPER - FRONT SINGLE PISTON .
  9. Support the brake caliper with heavy mechanics wire or equivalent.
  10. Remove the inboard brake pad, retainer spring and outboard brake pad. See Figure.
  11. Inspect the disc brake mounting and hardware. See DISC BRAKE HARDWARE - FRONT SINGLE PISTON  under ADJUSTMENTS & INSPECTION.
  12. Inspect the disc brake caliper. See DISC CALIPER INSPECTION  under ADJUSTMENTS & INSPECTION.
  13. Inspect the caliper bolts for corrosion or damage. Do not attempt to polish away any corrosion. If corrosion is found, use new parts, including bushings, when installing the caliper.
