Understanding Trailer Brake Systems
Before we dive into resetting your trailer brake system, it’s essential to understand how it works. Trailer brake systems come in two primary types: electric brakes and surge brakes.
Electric Brakes
Electric brakes are the most common type found on modern trailers. They utilize an electrical signal from the tow vehicle’s brake controller to activate the brakes on the trailer. The brake controller sends a current to the trailer brakes, which engage the brake shoes or pads against the drums or rotors, slowing down or stopping the trailer.
Surge Brakes
Surge brakes are simpler and less common than electric brakes. They rely on the momentum of the trailer during braking. When the tow vehicle brakes, the trailer continues moving forward due to inertia. This forward motion pushes a piston inside the brake chamber, activating the brakes on the trailer.

Common Problems with Trailer Brake Systems
While trailer brake systems are generally reliable, they can experience issues over time. Here are some common problems you might encounter:
- Brake Malfunction: One or more brakes on the trailer may not engage properly, leading to reduced stopping power.
- Dragging Brakes: The brakes may remain partially engaged, causing excessive wear and tear and overheating.
- Brake Fade: The brakes may lose effectiveness after repeated use, especially when towing heavy loads or descending steep hills.
- Wiring Issues: Damaged or corroded wiring can disrupt the electrical signal to the brakes, leading to intermittent or complete brake failure.
- Low Brake Fluid: Insufficient brake fluid can prevent the brakes from engaging properly.
Resetting Your Trailer Brake System
The specific steps for resetting your trailer brake system will vary depending on the type of system you have (electric or surge) and the specific issue you’re experiencing. However, here are some general guidelines:
Electric Brake System Reset
- Disconnect the Battery: Disconnect the negative terminal of the battery on your tow vehicle to prevent any electrical shocks.
- Check the Wiring: Inspect the wiring harness connecting the tow vehicle to the trailer for any signs of damage, corrosion, or loose connections. Repair or replace any damaged wiring.
- Adjust the Brake Controller: Refer to your brake controller’s manual for instructions on adjusting the gain and sensitivity settings. Proper adjustment ensures the brakes engage smoothly and effectively.
- Test the Brakes: Reconnect the battery and test the brakes by slowly applying the brakes on your tow vehicle. Listen for any unusual noises or feel for any uneven braking.
Surge Brake System Reset
- Inspect the Brake Chambers: Check the brake chambers on the trailer for any signs of damage, leaks, or obstructions. Ensure the pistons move freely and return to their original position.
- Adjust the Brake Linkage: Adjust the linkage connecting the surge mechanism to the brakes. The manual for your trailer will provide specific instructions on how to do this.
- Test the Brakes: Test the brakes by slowly applying the brakes on your tow vehicle. Observe the trailer’s response and ensure the brakes engage smoothly and effectively.
Preventive Maintenance for Trailer Brake Systems
Regular maintenance is crucial for ensuring the longevity and reliability of your trailer brake system. Here are some preventive measures you can take:
- Inspect the Brakes Regularly: Visually inspect the brakes on your trailer at least once a year, or more frequently if you tow heavily or in challenging conditions. Look for signs of wear, damage, or corrosion.
- Lubricate Moving Parts: Lubricate all moving parts of the brake system, such as the brake backing plates, brake hardware, and linkage components, with a high-quality brake lubricant.
- Check Brake Fluid Levels: Periodically check the brake fluid levels in the master cylinder of your tow vehicle and the brake chambers on the trailer. Top up the fluid as needed.
- Test the Brakes Frequently: Before each towing trip, thoroughly test the brakes on your trailer to ensure they are functioning properly.
