Ensuring Safe Travels: The Importance of Trailer Brake Maintenance

Posted by Thomas Hatts on

Are you gearing up for your next adventure with your trusty trailer in tow? Whether you're hauling goods for work or embarking on a recreational journey, ensuring the safety of your trailer should be a top priority. While many aspects contribute to trailer safety, one component stands out as particularly crucial: the trailer brakes. In this blog post, we'll delve into why trailer brake maintenance is essential and outline the necessary steps you should take annually to keep your trailer safe on the road.

Understanding Trailer Brakes

Before diving into maintenance routines, let's briefly discuss what trailer brakes are and why they matter. Trailer brakes are systems installed on trailers to assist in slowing down or stopping the trailer when it's being towed. They work hand in hand with the brakes of the towing vehicle, providing additional stopping power, especially when hauling heavy loads or navigating downhill terrain. There are several types of trailer brakes, including electric brakes, hydraulic brakes, and surge brakes, each with its own method of activation and control.

The Importance of Regular Maintenance

Just like the brakes on your car, trailer brakes require regular maintenance to ensure they function correctly when needed most. Neglecting maintenance can lead to brake failure, which poses serious risks to you, your passengers, and other road users. This is why annual maintenance routines are vital for keeping trailer brakes in optimal condition.

Annual Maintenance Checklist for Trailer Brakes

  1. Inspect Brake Components: Start by visually inspecting all brake components, including brake pads, rotors (if applicable), brake lines, and brake fluid reservoirs (if hydraulic brakes are installed). Look out for signs of wear, corrosion, leaks, or damage. Any worn or damaged parts should be replaced immediately.

  2. Adjust Brake Settings: Electric brakes may require periodic adjustment to ensure they're providing the proper braking force. Consult the manufacturer's instructions for adjusting the brake controller settings based on your trailer load and towing conditions.

  3. Test Brake Operation: Conduct a brake test to ensure all brakes engage smoothly and provide adequate stopping power. This can be done by towing the trailer in a safe, open area and applying the brakes to observe the trailer's behavior. If you notice any issues such as sponginess, unresponsiveness, or unusual noises, further inspection and adjustment are necessary.

  4. Lubricate Moving Parts: Lubricate any moving parts, such as brake caliper slides or surge brake couplers, to prevent corrosion and ensure smooth operation. Use a suitable lubricant recommended by the manufacturer.

  5. Check Brake Fluid (Hydraulic Brakes): If your trailer is equipped with hydraulic brakes, check the brake fluid level in the reservoir and top it up if necessary. Inspect the brake lines for leaks or damage and address any issues promptly.

  6. Inspect Electrical Connections (Electric Brakes): For trailers with electric brakes, inspect all electrical connections, including wiring harnesses, connectors, and brake magnets. Clean any corrosion and ensure secure connections to prevent electrical faults.

  7. Verify Emergency Breakaway System: Test the emergency breakaway system, which activates the trailer brakes in the event of a separation from the towing vehicle. Ensure the breakaway switch is functional, and the battery is charged.

  8. Wheel Bearing Maintenance: While not directly related to brakes, maintaining proper wheel bearing lubrication is crucial for overall trailer safety. Inspect wheel bearings annually and repack with grease as needed to prevent bearing failure.


Maintaining trailer brakes is a critical aspect of trailer safety that should never be overlooked. By following an annual maintenance routine and promptly addressing any issues that arise, trailer owners can ensure their brakes operate reliably and effectively. This proactive approach not only reduces the risk of accidents but also promotes safe travels for everyone on the road. Remember, when it comes to trailer safety, there's no substitute for regular maintenance. Safe travels!
