  5. Install a C-clamp over the body of the brake caliper, with the C-clamp ends against the rear of the caliper body and the outboard disc brake pad.
  6. Using the C-clamp, compress the piston into the caliper bore just enough to allow the caliper to slide away from the rotor.
  7. Remove the C-clamp.
    8. NOTE: Support the brake caliper with heavy mechanic's 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.
  8. Remove the caliper bracket bolts. Do not disconnect the brake flexible hose bolt.
  9. Remove the brake caliper and the caliper mounting bracket as an assembly from the suspension knuckle and support the assembly with heavy mechanic's wire, or equivalent. Ensure that there is no tension on the hydraulic brake flexible hose. Refer to Brake Caliper Bracket Replacement - Rear .
  10. Matchmark the position of the brake rotor to the wheel studs.
  11. Remove the brake rotor. Do not force the rotor off. If the rotor is difficult to remove, ease it off by gently rotating it as you pull outward.
