How to Reset Service Trailer Brake

If your lively hood depends on your truck, then knowing how to maintain it is also an essential aspect. One of the more common occurrences is your service trailer setting off. This can easily cost you over $100- $150 at a garage, why pay so much when you can do an easy DIY that’ll cost you below $50.

It’s a pretty simple process that requires tools that are readily available at any hardware store. We’re going to give you a step by step breakdown on how to service your trailer brakes. But before that, let us learn about trailer brakes.

Types of Trailer Brakes


There are two types of trailer brakes available in the market; these are surge brakes and electric brakes.

• Surge Brakes

These use a simpler self-contained hydraulic braking system; this relies mainly on the weight of the trailer and its momentum to help with braking. They don't rely on an electrical component; rather, it uses basic physics of compression to help transfer pressure to the brakes that, in turn, get the vehicle to a halt.
The simple mechanism means they require minimalistic effort. However, nothing is perfect; one of their major cons is the driver has limited control over the vehicle's braking.

• Electrical Brakes

As the name suggests, there are electrical components that you'll find in action on these brakes. Electrical power flows into the electromagnetic drums; in turn, this allows the brake pads to operate. With an electrical system, your brakes are customizable, allowing you to tune them according to your driving style.
However, to ensure the proper functionality of the brakes, a brake controller must be installed. Here’s where the problem lies as these electrical components need to be replaced time after time.

Tools Required

Some simple tools will be enough for the job, such as a brake adjustment tool; if you don't have that, then a flat head screwdriver will do you good. Except that you'll need the basic tools that are provided to help you take off the wheel.

Process

  • Before you start, get a good look at the instruction manual; each manufacturer does things differently; this will help you not mess up your truck.
  • Carefully remove the wheel to expose the brakes.
  • Get a hold of the "star wheel" adjuster located on your brakes. This should be attached to the brake shoes.
  • Next, using your brake adjustment tool or your screwdriver, tighten the adjuster till you are unable to spin the wheel.
  • Then take it back to a position where the wheel starts spinning freely again, without any resistance.

That's how simple the entire process is, and it should take you no more than 20mins each wheel to get the brakes to reset.
