How to Adjust Drum Brakes on Trailer

Having properly adjusted drum brakes on your trailer is essential for safe and efficient towing. In this article, we will guide you through the step-by-step process of adjusting drum brakes to ensure optimal performance.

Tools Required

Before you begin, gather the following tools:

  • Jack with jack stands
  • Lug wrench
  • Flathead screwdriver
  • Brake spoon (adjusting tool)
  • Wire brush
  • Ratchet with appropriate sockets

Step 1: Preparation

First, park your trailer on a level surface and engage the parking brake. If the trailer is coupled to a vehicle, disconnect it for safety.

Step 2: Lift the Trailer

Using a jack, lift the trailer wheels off the ground and secure them with jack stands to prevent any movement.

Step 3: Remove the Wheels

Using a lug wrench, loosen and remove the lug nuts from the wheels. Carefully take off the wheels and set them aside.

Step 4: Inspect Brake Components

Inspect the brake components for any signs of excessive wear or damage. Use a wire brush to remove any dirt or debris that may have accumulated.

Step 5: Adjust the Brakes

Locate the adjusting mechanism on each brake assembly. Most drum brakes have a small rubber plug on the backside of the backing plate. Remove the plug with a flathead screwdriver.

Step 6: Adjust the Brake Shoes

Using a brake spoon or adjusting tool, turn the star wheel adjuster. Rotate it upwards to tighten the brake shoes against the drum and downwards to loosen them. Keep adjusting until you feel a slight drag on the drum when spinning it by hand.

Step 7: Verify the Adjustment

After adjusting both brakes, give the drums a few turns to ensure they rotate smoothly without excessive drag or binding. If necessary, make further adjustments until you achieve the desired balance.

Step 8: Replace Components

Once you are satisfied with the brake adjustment, place the wheels back onto the trailer and secure them with the lug nuts. Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Step 9: Lower the Trailer

Using the jack, carefully lower the trailer back to the ground and remove the jack stands.

Step 10: Test the Brakes

Take your trailer for a short test drive to ensure the brakes are functioning correctly. Pay attention to any unusual noises or vibrations, which could indicate an improperly adjusted brake.

Remember, it is crucial to periodically check and adjust your drum brakes to maintain their effectiveness. Following these steps will help ensure your trailer’s brakes are in optimal condition, providing you with a safe and worry-free towing experience.

Now that you know how to adjust drum brakes on a trailer, it’s time to put your knowledge into practice and ensure your safety on the road!
