How To Adjust Brakes On Semi Trailer?

Here are the basic steps to adjust brakes on a semi trailer:

First, park the trailer on a level surface and chock the wheels to prevent movement.

Remove the dust cap from the brake drum.

Use a brake adjusting tool to reach inside the drum and turn the adjusting star wheel in a clockwise direction to tighten the brake shoes against the drum.

Tighten the shoes until you feel resistance from the brake drum.

Then, turn the star wheel back 10-15 times counterclockwise to provide proper clearance between the brake shoes and the drum.

Put the dust cap back on the brake drum to protect it from debris and moisture.

Finally, make sure to test the brake performance by applying the brakes and checking for proper stopping distance and smooth operation.

It's important to remember that brake adjustment should be done regularly, as poorly adjusted brakes can compromise safety and lead to accidents.
