Air leak

Your truck’s air system is its lifeline. If your gauge won't build pressure past 60 PSI, or if you can hear the hiss of escaping air over the sound of your engine, you are not just stuck—you are a DOT violation waiting to happen. Expert Mechanic Services specializes in the pneumatic systems of heavy-duty trucks. We don't just "tape it up." We trace leaks from the compressor to the brake chambers using advanced detection methods. Whether it’s a blown air bag, a cracked airline, a faulty governor, or a leaking glad hand, we carry the fittings and hoses needed to fix it permanently on the roadside. We ensure your system builds air fast and holds it steady.
