Electric trailer brakes are commonly found on caravans and camper trailers in Australia due to their affordability and simple design. They use electrical signals, electromagnets, and brake pads to aid in the deceleration of the trailer while towing. It is important to adjust your trailer brakes regularly for safety reasons. This involves jacking up the trailer, accessing the brakes, using an adjustment tool, and testing for tire lockup. The star wheel adjuster, located below the brake drum, can be turned with a brake spoon, adjustment tool, or flathead screwdriver to tighten or loosen the brake pads.

What You'll Learn
Jack up the trailer and access the brakes
Jacking up the trailer is an important first step in adjusting your trailer brakes. This process should be done every 3,000 miles or 3 months, ensuring safe towing.
To begin, you'll need to raise the trailer until the trailer wheel can be freely moved and spun. This can be done by using a jack to lift the trailer on a flat, level surface. It is important to place a chock under the wheel opposite to the one you are adjusting to prevent any accidental movement. If your trailer has a handbrake, make sure it is disengaged.
Once the trailer is securely in place, you can access the brakes. To do this, remove the adjuster dust cap, which can be done by hand or with a screwdriver. This will expose the star wheel adjuster, typically located below the brake drum. With the right tools, you can now begin the process of adjusting the brakes.
The star wheel adjuster is the component that controls the clearance between the brake shoe and the drum. By turning this wheel, you can push the shoes closer to or further away from the drum, depending on the direction you turn it. It is important to adjust the brakes so that the trailer tire turns freely with a slight scraping sound, indicating proper engagement.
With the trailer jacked up and the brakes accessible, you can now move on to the next steps of adjusting your electric trailer brakes.

Use a brake spoon or screwdriver to adjust the star wheel
To adjust the star wheel with a brake spoon, you'll first need to jack up the trailer so that the trailer wheel can be spun freely. Then, use a jack or axle stand to secure the trailer. Make sure to do this on a flat, level surface with a chock under the wheel opposite to the one you're adjusting. If your trailer has a handbrake, make sure it's disengaged.
Now, remove the dust cap to access the star wheel. If this is difficult to do by hand, you can use a screwdriver. Once you have access to the star wheel, you can use the brake spoon to turn the star wheel adjuster inside the brake chamber. Push down on the brake spoon handle so that the adjuster wheel is pried upward, tightening the brake pads or shoes.
Turn the wheel one click at a time. After each click, spin the tire to make sure it spins freely. Once the trailer tire becomes difficult to turn, stop tightening the adjuster. If you need to loosen the adjuster wheel, simply pry upward on the brake spoon. The tire should spin freely but still have a slight scraping sound, indicating that the trailer brake pads are properly engaged.

Spin the wheel to check the brakes
When adjusting electric trailer brakes, it is important to check that they are working effectively. One way to do this is to spin the trailer wheel to see if it moves freely.
Firstly, you will need to raise the trailer until the wheel can be spun freely. Place a jack under the trailer frame, not the axle, and jack it up until the wheel spins without obstruction. It is important to do this on a flat, level surface with a chock under the wheel to stop the trailer from moving. Secure the trailer with a jack stand. If your trailer has a handbrake, make sure it is disengaged.
Then, use a screwdriver to remove the adjuster dust cap and access the star wheel adjuster. Using a trailer brake spoon, brake adjustment tool, or flathead screwdriver, turn the star wheel adjuster inside the brake chamber. Push down on the brake spoon handle so the adjuster wheel is pried upward, tightening the brake pads. Turn the wheel one click at a time, and spin the wheel after each click to check that it still spins freely.
Once the trailer tire becomes difficult to turn, stop tightening the adjuster. The tire should spin freely but still have a slight scraping sound, indicating that the trailer brake pads are properly engaged. If the adjuster needs to be loosened, pry upward on the adjustment tool.

Test for tire lockup
Testing for tire lockup is an important step when adjusting electric trailer brakes. Here is a detailed guide on how to perform this test:
Step 1: Warm up the Trailer Brakes
Before starting the test, it is important to warm up the trailer brakes by applying the brakes several times. Warming up the brakes helps to ensure that they are in optimal condition for the test.
Step 2: Adjust the Gain
After warming up the brakes, you can begin adjusting the gain setting on the trailer brake controller. The gain setting controls the amount of power applied to the trailer brakes, and it should be adjusted until the trailer tires lock up. This step should be approached with caution, as performing it at high speeds or for an extended period can cause flat spots on the trailer tires.
Step 3: Reduce Gain to Prevent Tire Lockup
Once you have determined the point at which the trailer tires lock up, it is crucial to reduce the gain setting. Adjust the gain until the tires no longer lock up. This ensures that the trailer brakes are set correctly and safely.
Step 4: Fine-tune the Settings
Finally, you can fine-tune the settings to achieve optimal braking performance. Some people prefer to set the brakes slightly lighter so that they barely feel the trailer brakes. Others aim for as much trailer brake power as possible without causing tire lockup. This setting may vary depending on the load and conditions.
It is important to note that the specific steps for adjusting electric trailer brakes may vary depending on the make and model of your trailer and brake controller. Always refer to the user's manual or seek professional advice if you are unsure about any aspects of the adjustment process.

Check the torque on trailer tire nuts
When adjusting electric trailer brakes, it is also a good idea to check the torque on your trailer's tire nuts. This process should be repeated any time the lug nuts are removed from the wheel or after the first 10, 25, and 50 miles, and periodically during normal use.
To do this, follow a star pattern and make sure each one is torqued to the manufacturer's specifications. You can determine the torque rating for the lug nuts on your trailer by referring to a lug nut torque chart, which details the recommended torque for various combinations of stud and wheel diameter, wheel material, and wheel size. For instance, for 15-inch trailer rims, 90-120 ft lbs of torque is likely appropriate, while for 9/16 inch studs, the typical lug nut torque will be 120-140 ft lbs.
It is important to use a properly calibrated torque wrench to check the torque values. The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18.
