A brake controller is usually an original equipment manufacturer or aftermarket-installed device or module. It is mounted to the tow vehicle's driver's-side dashboard area, and engages a trailer's electrical braking system either time delayed, or in proportion to the tow vehicle's brake engagement when slowing down or coming to a halt. A brake controller is not needed with a trailer surge braking system unless using modern electric over hydraulic devices. The trailer in this case usually has either electric friction brakes or electric-hydraulic trailer brake actuators.
Most basic brake controllers will generally have a plus-minus gain adjustment. The tow vehicle operator sets the gain as high as possible but without the trailer brakes locking up after making a few test stops. The heavier the trailer, the higher the gain adjustment is set and therefore the less chances of wheel lock-up.[1]
A wide range of trailers contain trailer brakes (for example, larger boat trailers, horse trailers, covered utility trailers, enclosed trailers, travel trailers including small 10-foot or 3.0-metre and longer tent trailers and car carriers). Smaller trailers may not contain trailer brakes (for example, basic 4-by-8-foot or 1.2-by-2.4-metre utility trailers). It is recommended that, if the total trailer weight is over a couple thousand kilograms, the trailer have some sort of braking system, and the tow vehicle be equipped with a brake controller.[2][3]
Types
[edit]There are different types of brake controllers currently or previously on the market.
- Air-actuated electric brake controller
- This controller uses the air pressure of the brake system on a vehicle with pneumatic brakes to provide a current to control the electric brakes of a trailer.[4]
- Hydraulic-actuated electric controller
- This controller uses the hydraulic pressure of the brake system on a vehicle with hydraulic brakes to provide a current to control the electric brakes of a trailer.[5] Some truck manufacturers offers this as an OEM option, like Ford with its Ford TowCommand.
- Pedal-mounted pressure pad proportional controller;
- A separate sensor is mounted on the brake pedal to connect to the controller.[6]
- Proportional brake controller
- Senses the deceleration of the vehicle through a pendulum or similar device to apply a suitable current for braking of the trailer.[7][8][9]
- Surge brake
- When the tow vehicle slows down the trailer pushes against it, an actuator applies force to its master cylinder and the hydraulic pressure is transferred to the brakes[10]
- Time-delayed brake controller
- Applies brake current with a ramp-up over time to a certain level set by the driver.[8][9][11]
