  7. Remove the brake caliper guide pin bolts.
    8. CAUTION: Do not depress the brake pedal with the brake rotors/calipers and/or the brake drums removed. Damage to the brake system may result. If brake system damage occurs and is not repaired, vehicle damage and/or personal injury or death may result.
    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.
    NOTE: Refer to Brake Caliper Notice .
  8. Remove the brake caliper from the brake caliper bracket and support with heavy mechanics wire or equivalent.
