How to Adjust Electric Brake Controllers


An electric brake controller is a necessary safety feature when towing a heavy trailer. Expecting your tow vehicle to provide all of the braking needed to stop the entire rig may be asking for trouble. An electric brake controller installed in your tow vehicle applies the trailer brakes automatically when the tow vehicle’s brakes have been applied. Most brake controllers will apply only the amount of braking needed, depending on speed, the amount of pressure applied to the brake pedal and the rate of deceleration. If your electric brake controller is not adjusted properly, the trailer brakes may grab, skid or not work at all.

Step 1

Connect the trailer to the tow vehicle. Plug in the trailer’s electrical connection to the receptacle near the trailer hitch on the rear of the tow vehicle.
