  11. Mark the relationship of the rotor to the hub.
    12. 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.
  12. Remove the brake caliper and brake caliper mounting bracket as an assembly and support with heavy mechanic's wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper.
  13. Remove the rotor retaining push nuts from the wheel studs, if applicable.
  14. It may be necessary to strike the end of the hub or the rotor with a deadblow hammer to separate the rotor from the hub.
