Adjusting your Trailers Surge Brakes

There are two major types of braking system used at different types of trailers: those are the electrical brakes controlled by a controller in the tow vehicle and of course, the surge brakes that have no rely on the tow vehicle. They use brake fluid that comes through the master cylinder to the brakes. It’s important to adjust the brakes regularly.

Follow these steps:

  1. Decide on what wheel you will work first and block the opposite with chocks. Lift the car using a floor jack and place it on jack stands.
  2. At the most rear wheel locate beneath the trailer the clip covering adjustment hole. You must pry the clip off.
  3. Put in the inspection hole a drum brake adjustment tool or a flat head screwdriver until it touches the star wheel.
  4. While rotating the wheel and tire in the forward driving direction, use the screwdriver to turn clockwise the star wheel until the wheel is stopped by the braking pressure.
  5. After that point reverse the star wheel 5 notches and test the wheel to rotate freely. Mount back all the pieces starting with the clip, then the wheels and lower the car to the ground.
  6. Follow the same steps for the other side.
