As a truck driver, maintaining your truck’s brakes is crucial to ensure safety on the road. Adjusting the brakes of your semi-truck is an essential maintenance task that you should perform regularly. In this article, we will guide you on how to adjust your semi-truck brakes.
Why Adjusting Semi-Truck Brakes is Important
Adjusting your semi-truck brakes helps you maintain the correct clearance between the brake shoe and the drum. Over time, the brakes can become out of adjustment, which can lead to brake failure and cause accidents. Regular adjustment of your semi-truck brakes will help you avoid this kind of situation.
Step-by-Step Guide to Adjusting Semi-Truck Brakes
Here are the steps to adjust your semi-truck brakes:
Step 1: Park the Truck on a Flat Surface
First, park your truck on a flat surface and engage the parking brake. Make sure the wheels are blocked to prevent the truck from moving.
Step 2: Remove the Wheel
Next, remove the wheel that you need to adjust. Use a lug wrench to loosen the lug nuts and then lift the truck with a jack. Once the wheel is off, you can access the brake assembly.
Step 3: Locate the Brake Adjuster
Locate the brake adjuster and turn it with a brake adjusting tool until the brake shoe is in contact with the drum. Turn the adjuster back slightly to allow for clearance between the drum and the brake shoe.
Step 4: Reassemble the Wheel
Reassemble the wheel and tighten the lug nuts. Lower the truck and repeat the process for the other wheels.
