2. Electric brakes incorporate electromagnets inside
the brake drums which actuate the brake shoes, in
proportion to the amount of voltage put across the
system. For this system, a brake controller must be
installed in the tow vehicle and connected to the
tow vehicle's braking system. Some systems are
connected directly to the tow vehicle's hydraulic
brake lines. These systems provide smooth, well
controlled stopping but can suffer from leaks or
hydraulic mess. Many vehicles with anti lock brake
systems will not operate efficiently with the
hydraulic type of brake controller. For these
users, an electronic brake controller is necessary.
These units detect when the brake pedal is pressed
and control the trailer braking through the use of
pendulums or accelerometers. Advantages of the
electric brakes are the simplicity of the braking
system and the fact that the trailer brakes can be
actuated independently. Disadvantages include the
fact that the tow vehicle has to be wired for the
electric brakes and that bad wiring can cause a
brake system failure.
