14. Remove the brake caliper and bracket assemblies from the rear axle and support them with heavy

mechanics wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper.

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.
