Trailer Brake Maintenance Guide

When it comes to transporting your cargo, you want to make sure that you have got the right brakes installed on your trailer and they’re in top shape. A little proactive maintenance can go a long way in keeping your rig safe on the road and out of the mechanic's shop. While there are some steps best left to a professional, there are still plenty of steps even a novice can handle. Below we cover some basic trailer brake maintenance practices and tips.

Types of Trailer Brakes

If you want to take proper care of your brakes, you need to know more about how different types of brakes work. Electric brakes use an electric connection that sends a signal from the tow vehicle to the trailer brakes. When you press the pedal brake, you trigger the signal, which activates your trailer brakes. 

Surge brakes are triggered when you slow down your trailer and there’s a forward jolt. On sensing that the trailer is shifting forward, the system automatically activates the brakes to prevent the trailer from slamming into the back of the tow vehicle. These brakes are good for those who spend a lot of time around water because you won’t have to worry about your electrical systems getting fried.

Inspection

Always remember to thoroughly inspect your trailer’s brakes before you hit the road. Check every part of the braking system and look for signs of damage on the drums, shoes, shoe return springs, and hardware. When comparing both sides of the braking system, you might find the brakes to be wearing unevenly, which means there might be an issue that needs immediate attention. This could either be a sign that you’re not loading your trailer correctly or there’s something wrong with the hitch.

If your unit has an independent braking system, get rolling slowly and apply the brakes. If you hear a screeching or grinding noise, or if the trailer pulls to one side or the other, you know you have a problem. Check the wiring harness on your trailer and make sure that the brake and turning lights are bright and strong, not flickering or dull.

Specific Problems

Different brake systems can be checked in different ways. For electric brakes, you’ll need to check the wiring and connections to ensure that there are no breaks or frays. If you have surge brakes, try and push your trailer to see if the braking system activates. If it doesn’t, you might have an issue with the brake fluid, the master cylinder, or wheel cylinders. 

Regular Maintenance

Regular inspections should be performed on a yearly basis or after every 12,000 miles. If you don’t use your trailer often, make sure to check your brakes before every trip. If your rig remains idle for a long time, take it out for a spin every two or three months. This way, all the parts will get some exercise and you can avoid issues that arise due to disuse.
