These are especially beneficial for towing a vehicle. The brake controller is an external device, installed on the dash of the vehicle that is towing another vehicle. When the driver of the towing vehicle applies the brake, a message is electronically transmitted to the brakes of the towed vehicle that it must stop.

When the towing vehicle applies the brake, the towed vehicle continues to move at the same velocity and causes a domino effect which is a great threat to the safety of both the vehicles. There are two kinds of the brake controller. The Time-delayed one applies a pre-determined pressure on the brakes of the towed vehicle.
