Air System Integrity: Fixing Air Leaks and Brake Lines

Air leaks are the most common cause of trailer-related DOT stops in Sun Prairie. The constant vibration and exposure to the elements on WI highways can cause air brake lines to chafe or fittings to crack.

We perform meticulous leak detection, ensuring that your system holds pressure according to legal requirements. If you have a blown brake chamber or a failing slack adjuster near 53590, we can perform the replacement on the shoulder. We also provide reefer trailer repair support for air-operated systems, ensuring your refrigerated unit doesn't compromise your tractor's air supply at 43.19462200, -89.20792000.
