Understanding Trailer Brake Controllers

An electric trailer brake controller is a device that supplies power from a tow vehicle to a trailer's electric brakes. There are two types of brake controllers on the market today – Time Delay Activated and Inertia Activated.

While the controllers operate differently, they are very similar. Both types have the same wiring configuration. Both allow the driver to adjust the amount of braking power and both have a pressure-sensitive manual override switch that can be used to apply the trailer brakes independently of the tow vehicle.

Time Delay Activated Brake Controls

Time Delay Activated or "solid-state" controllers are enabled by the depressing of the brake pedal in the tow vehicle. Once enabled, time delay activated controllers apply a gradual voltage to the trailer's brakes using a Time Delay Circuit.

The advantages of a solid-state brake control unit are the inexpensive cost, low profile, and they can be mounted at any angle. The disadvantages mostly pertain to Hazard Flashers issues. In most applications, the digital display will flash with the hazard flashers and if the gain is set aggressively, some pulsing of the trailer brakes may be felt.

Hazard Flasher issues can be resolved by using a Pulse Preventer that will isolate the brake control from the vehicle's flashers, thus eliminating the pulsing.

Inertia Activated Brake Controls

Inertia Activated Brake Controllers or Pendulum Style controllers are enabled by the depressing of the brake pedal and activated by a Pendulum Circuit that senses the stopping motion of the vehicle. The Pendulum Circuit applies a proportional voltage to the trailer's brakes.
