    NOTE: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brakes 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.
  16. Support the calipers from the frame using a heavy gauge mechanics wire.
  17. Remove the nuts and the washer from the spring assembly U-bolts.
