Tie Down Drum Brakes - Manual (Page 7)

Electric Drum Brake Information
Electric brakes are activated by a brake controller located in the tow vehicle. This is
generally an accessory that must be purchased separately. Please research before
buying. Some controllers work better with different brand tow vehicles.
Electric drum brakes are not recommended for marine applications.
Electric brakes are individually adjusted in the same way the hydraulic drum brakes
are adjusted, which is covered in this manual. The electric drum brakes work by an
electrical current going to the brakes and activating a magnet. The magnet is then
attracted to the inside wall of the drum hub. This drags the magnet and pushes the
brake shoes out against the drum hub. The brake controller is generally adjustable to
regulate the amount of current given to the magnets/drum brakes. This adjustment
controls the amount of braking force applied.
Wires are connected to the brakes by one of two methods:
1. Plug in wires.
2. Twist wires with a wire cap cover.
There is not a specified positive/negative connection at the brakes.
