5. Remove pads from caliper.
6. Remove caliper from vehicle.

1. Install brakeshoes in caliper.
2. Connect brake hose fitting to caliper but do not tighten fitting bolt completely at this time. Be sure to use new washers on fitting bolt to avoid leaks.Install caliper. Position mounting notches at lower end of brakeshoes on bottom mounting ledge. Then rotate caliper over rotor and seat notches at upper end of shoes on mounting ledge.
