FAQ: Air Brake & Suspension Repair
What causes trailer air pressure to drop when parked?
Pressure drop usually comes from a leak at a fitting, service line, valve, or brake chamber. We isolate the circuit, pinpoint the leak source, then repair the failed component to stop the bleed-down.
Can you fix a leaking brake chamber on-site in West Sacramento (95691)?
If the leak is from an internal diaphragm, the chamber must be replaced. We commonly replace Type-30/30 chambers on-site for yard-based fleets in 95691.
What are the signs of bad trailer suspension?
Look for dog tracking, uneven tire wear, clunking, sagging ride height, or rust streaking around spring packs. Cracked air bags and worn bushings also cause instability—common on agricultural routes near Woodland (95776).
Do you inspect pintle hooks for doubles fleets?
Yes. We use a wear gauge and check pintle couplers, drawbars, and safety chain condition for doubles fleets because worn couplers are a high-liability safety issue.
