Brake controls are
designed to apply the brakes of the towed vehicle (trailer).
There are three types of brake controls on the market today
timed, inertia, and proportional. Another type of braking system
that is used for trailers is a breakaway kit.
Timed
Controls
Timed based controls generate an output signal that increases
over a period of time. The time based controls apply braking
power at the fixed rate that is not proportional to the pressure
applied to the brake pedal.
Proportional
Controls
Proportional based controls offer a smooth braking response to
almost any stop. Through the use of a sensing device, the brake
control can determine the tow vehicle's rate of deceleration and
then apply the trailer brakes to match. In other words,
Proportional controls deliver power to the trailer brakes in
direct relationship to the actual physical deceleration of the
tow vehicle.
