Air Brake Service & Repair
Brakes put more trucks out of service at the roadside than anything else, year after year. They are also the single most predictable repair on a truck — the wear is measurable, so there is no excuse for being surprised by it.
What we do
- Full brake jobs — shoes, drums, hardware and seals, per axle
- Slack adjusters, automatic and manual, set to spec
- Brake chambers and spring brakes, including caged and dragging units
- Air lines, valves, governor, dryer and the leaks that cause slow build-up
- ABS fault diagnosis and repair
- Push-rod stroke measured and documented, not eyeballed
Symptoms worth stopping for
- Air pressure building slowly, or the compressor cycling constantly
- A brake that grabs, drags, or runs hot on one wheel end
- Pulling to one side under braking
- Squeal, grind, or a pedal that has gone soft or long
- Any audible leak with the parking brake set
A dragging brake is not just a violation — it cooks a wheel end, kills a tire and can start a fire. If a wheel is running hot, stop.
The out-of-service math
A brake violation at a roadside inspection stops the truck where it stands, puts a mark on your CSA score, and costs you the load. A brake job scheduled on your own terms costs shop time you chose. There is no version of this where deferring is the cheaper option.
Bring it in with the DOT annual and both get handled in one visit off the road.

Questions we get asked
How long does a brake job take?
A per-axle job is typically a few hours. We quote the full number before we start and tell you if anything else on that wheel end needs to come apart.
Do you work on trailer brakes too?
Yes — tractors and trailers, including spring brakes, ABS and air-system faults.
My air builds up slowly. Is that serious?
It usually means a leak, a tired compressor or a failing dryer. It is worth diagnosing right away — slow build-up is the warning before you have no brakes at all.
Can you fix a brake problem found in an inspection?
That is exactly what we do. Failed items from a DOT inspection get repaired in the same bays the same visit.
