A trailer problem can stop a load as fast as an engine failure. Our service trucks carry trailer parts and diagnostic tools, so most repairs happen in one visit.
Air brake defects are the top reason trailers fail inspection. We repair:
Federal rules require ABS on air-braked trailers built on or after March 1, 1998. Those trailers also need an outside ABS warning lamp, per 49 CFR 393.55. The lamp should turn on at power-up, then go out. A lamp that stays on, or never lights, is a violation.
We plug into the ABS module and read the fault codes. The usual causes are a failed wheel speed sensor, a damaged tone ring, a bad modulator valve, or corroded wiring. ABS also needs constant power from the tractor. A trailer ABS light that acts up often traces back to a worn 7-way plug or a bad ground.
Bent legs, stripped gearboxes, and broken crank handles strand trailers at docks and drop yards. We repair and replace landing gear on location, including SAF-Holland and JOST units. If the trailer is loaded, we support it safely before we pull a leg.
Dead tail lamps, stop lamps, and marker lights get trailers stopped at scales. We trace shorts, replace corroded pigtails and 7-way sockets, and repair wiring harnesses. We swap burned-out lamps with LED units that hold up better on the road.
A flat or leaking trailer tire can put the whole rig out of service. We change trailer tires on-site, repair valve stems, and stock common trailer sizes. For truck breakdowns and tire failures on the tractor, see our 24/7 roadside truck repair service.
Call (682) 231-8338 any time, day or night. A live dispatcher will send a mechanic to your trailer.
A trailer placed out of service can’t move until the repairs are done. Federal rule 49 CFR 396.9 bans operating it, except by crane or hoist tow. That makes mobile repair the fastest way off the scale lot.
These defects commonly put trailers out of service under the CVSA Out-of-Service Criteria:
| Defect | Why it matters | Fixed on-site? |
|---|---|---|
| 20% or more of service brakes defective | Places the vehicle out of service | Yes |
| Audible air leak at a brake chamber | Counts as a defective brake | Yes |
| Brake stroke beyond the adjustment limit | Counts toward the 20% rule | Yes |
| Flat tire or audible tire leak | Out of service on the spot | Yes |
| Missing tail or stop lamps on the last trailer | Can be out of service, mostly at night | Yes |
| ABS lamp on or not working | A violation, but not out of service | Yes |
After the repair, you get a written invoice listing each defect and fix. Carriers must certify repairs and return the inspection report within 15 days. Our invoice gives your safety team the proof it needs.

Cost depends on the repair, the parts, and the time of day. A light repair costs less than a set of brake chambers. Our dispatcher explains the dispatch fee and rates by phone. The technician quotes the repair before starting.
The most common causes are a failed wheel speed sensor, a damaged tone ring, or a wiring fault. A worn 7-way plug that cuts constant power can also trigger it. We read the ABS fault codes to find the exact cause.
