The Dexter 12-1/4" x 2-1/2" Right Hand Electric Manual Adjust Brake is the perfect solution for those looking for a reliable and easy to use electric brake system. This brake assembly comes with a loaded backing plate, ready to mount and requires a brake controller for operation. Electric brake systems offer more user control compared to hydraulic systems and with this brake assembly, brake lines and actuator are not necessary for operation. The non-polarized magnet allows either wire to be used as ground or power supply, making installation and operation a breeze. FleetPride is your First Click in Heavy Duty®.
