Start by parking your service trailer on a flat surface. Make sure the trailer is in neutral, the parking brake is disengaged, and the tires are inflated to the manufacturer’s recommended pressure.

Once the trailer is properly positioned, you will need to gather the following tools: adjustable wrench, socket set, and a flathead screwdriver. These tools are necessary in order to access the brake system and make any necessary adjustments.
To reset the brake system, begin by removing the wheels from the service trailer. Loosen the lug nuts with the adjustable wrench and then remove the wheels with the socket set. Once the wheels are removed, locate the brake lines, which will be located between the frame and the axle. Disconnect the brake lines and remove the caliper from the axle.
Once the caliper is removed, use the flathead screwdriver to adjust the brake shoes. Adjust the brake shoes until they are tight against the brake drums. You may need to use a torque wrench to ensure that the brake shoes are properly tightened. Once the brakes are adjusted, reattach the caliper and the brake lines. Finally, reattach the wheels and tighten the lug nuts.
Now that the brake system has been reset, it is important to check the brakes for proper alignment and operation. To do this, slowly drive the service trailer a short distance and then check the brakes for any unusual noises or vibrations. If everything is working properly, the brakes should be adjusted and ready for use.
Resetting the service trailer brake system is not a difficult task, but it is important to take the time to make sure the brakes are adjusted and working properly. Following these steps will ensure that your service trailer brake system is operating at its best and will help you avoid any costly repairs in the future.
