Air brakes, by the book
Run the air check.
The five-step air brake check from the CDL manual, on a working gauge. Tap a step and watch what a healthy system does.
At fast idle, a dual air system should climb from 85 to 100 psi in about 45 seconds.
The compressor should stop pumping around 125 psi, then cut back in around 100 psi as you use air.
Engine off, brakes released: lose under 2 psi in a minute on a straight truck, under 3 on a combination. Brake held down: under 3 and 4.
Fan the brakes down. The low-air warning should come on before the gauge drops below 60 psi.
Keep fanning. The parking brake and trailer air supply knobs should pop out between 20 and 45 psi.

Drivers we’ve put back on the road.
Marc is a reliable and honest person to do business with. I was stuck on the road for 4 hours until I called him and he was able to get me back on the road as soon as possible. Called him back for a follow up inspection on another truck and was able to fix it and hasn’t given me additional problems since.
Excellent Mechanic who really knows his stuff. If he can’t figure it out, no one can. Friendly, extremely competent and just the man you’re looking for no matter how large or small the job is.
