  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 suitably support the vehicle. Refer to Lifting and Jacking the Vehicle .

  7. Install a large C-clamp over the body of the brake caliper with the C-clamp ends against the rear of the caliper body and against the outboard brake pad.
  8. Tighten the C-clamp evenly until the caliper pistons are compressed into the caliper bores enough to allow the caliper to slide past the brake rotor.
  9. Remove the C-clamp from the caliper.

  11. To loosen the brake caliper lower pin bolt, hold the brake caliper guide pin with a wrench.
  12. Remove the brake caliper pin bolt.
  13. NOTE: 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.
  14. Pivot the brake caliper body (1) upward and secure the caliper out of the way with heavy mechanic's wire or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose. Do NOT disconnect the hydraulic brake flexible hose from the caliper.
