A brake piston system for pushing a brake piston into a brake caliper includes a housing including a handle section and a main section is coupled to the handle section. The handle section is graspable by a person. A backing plate is coupled to a front end of the housing. The backing plate is abutted against a front plate of the brake caliper. A ram assembly is mounted to the housing and extends through the backing plate. The ram assembly is abuttable against the brake piston of the brake caliper when the backing plate is abutted against the front plate. The ram assembly is actuated to push against the brake piston and force the brake piston into the brake caliper. An actuation assembly is coupled to the housing. The actuation assembly is actuated to actuate the ram assembly to advance the brake piston into the brake caliper.
