§ 02 Our approach
How we handle air brake repair
Air brakes are a system: compressor, dryer, tanks, valves, lines, chambers, slack adjusters and foundation brakes all have to work together. We start with an air system check — build-up time, governor cut-in and cut-out, leak-down — then measure pushrod stroke at every wheel end with the brakes applied.
Repairs cover shoes, drums, hardware, cams and bushings, chambers and spring brakes, automatic slack adjusters, relay and quick-release valves, air dryers and leaking lines or fittings. Automatic slacks that keep going out of adjustment usually point to a worn foundation component; we fix that cause instead of just re-adjusting.

§ 05 FAQ
Air Brake Repair questions
How often should air brakes be checked?
Brake adjustment should be checked as part of every pre-trip, and a full brake inspection is a good idea at every PM service. High-mileage and stop-and-go units may need attention more often.
Do you repair trailer brakes too?
Yes. We work on tractor and trailer brake systems, including spring brakes, relay valves, gladhands and ABS on trailers.
Can brake work be done at our yard?
Most brake jobs — adjustments, chambers, slack adjusters, shoes and leaks — can be done at your location as long as there is a safe, level place to work.
