You will need a tool to screw in the rear caliper piston if equipped with the type of parking brake that actuates the pad, if it is the internal shoe type no special tool is needed to retract the piston. I would suggest using a clear neoprene tube from the caliper bleeder to a jar of brake fluid, back ff the bleeder and retract the caliper pistons this way to avoid possible contamination of the abs unit.
