Drum Brakes Explained
Most heavy-duty trucks use drum brakes as they’re generally more effective than the disc variety. To start the braking process, compressed air will enter each brake assembly's service chamber. The air will push on a diaphragm within the chamber, which in turn moves a push rod forward. The movement of this pushrod results in your q-cam rotating, which in turn causes your brake shoes to travel outwards. This allows your brake pads to make contact with each brake drum, which brings your truck to a stop.
Brake Adjusters Explained
When brake drums were first developed, they encountered an issue. As a truck’s brake pads wore down, each part of the brake assembly would have to move a lot farther before contact could be made with the drum. To solve this problem, the brake adjuster was added to the assembly. Brake adjusters are designed to take up the excess slack, therefore allowing your brakes to be fully effective regardless of how much brake pad life you have left. Although brake adjusters are automatic, they may malfunction over time and require manual calibration by a trained professional.
