  15. Remove the brake calipers. Refer to Brake Caliper Replacement - Rear (1500 Series) or Brake Caliper Replacement - Rear (2500/3500 Series) in Disc Brakes.
    16. 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.
