Mobile Brake, Suspension and Pneumatic Repair for Tractors and Trailers
From a slow leak in the yard to a brake failure on the shoulder, our mobile mechanics inspect, adjust and rebuild air brake systems wherever your trucks are. Problems get fixed before they turn into an out-of-service order.
What We Do
Repair and replacement of brake chambers, valves, air lines and governors on tractors and trailers.
Full air brake rebuilds in your yard, plus emergency roadside brake repair through 24/7 dispatch.
Pushrod stroke measured and brakes adjusted to spec, included in every PM-A.
Air leak-down tests, governor cut-in and cut-out checks, and gladhand seal inspection.
Brake shoe and drum thickness measured during PM-C, so wear is caught before it fails inspection.
Trailer air bag, ABS diagnostic and relay valve repair for dry vans, reefers and flatbeds.
Inspection and repair of wheel ends, steering linkage and related pneumatic components.

Brake Safety
Brake defects are one of the most common reasons trucks get placed out of service at roadside inspections. Most start small and cost little to fix in the yard. On the scale, they cost you the truck, the load and a mark on your CSA score.
Warning Signs
Slow air build-up or pressure loss while parked
Audible air leaks
Pulling or uneven braking
Low-air warnings
Uneven trailer ride or a failing air suspension
ABS warning lights
