Brakes are the one system you never gamble on. On a loaded rig, a slow leak or a worn chamber isn’t just a repair waiting to happen — it’s a DOT violation and a safety risk every mile you run it. J&A Fleet diagnoses and repairs heavy-duty air brake systems the right way, mobile on the roadside or in our shop, with Bendix-trained techs who know these systems cold.
WHAT WE REPAIR
- Air chambers and brake cans
- Slack adjusters and S-cams
- Valves — relay, quick-release, treadle, and governor
- Air lines, fittings, and leaks
- Air dryers and compressor issues
- Shoes, drums, and disc components
- ABS faults and warning lights
- Frozen and locked brakes in winter
FROZEN BRAKES — COLD-WEATHER SPECIALISTS
Illinois winters are hard on air systems. Moisture in the lines freezes, brakes lock up, and a truck that parked fine won’t move in the morning. We thaw and free frozen brakes safely, find the moisture source so it doesn’t keep happening, and get you rolling without damaging components by forcing them. If you’re stuck in the cold, that’s a call we take seriously and answer fast.
HOW WE WORK
We find why the system is failing, not just the symptom. A brake that drags or grabs can trace back to a valve, a leak, or an adjuster — and replacing the wrong part leaves you with the same problem and a bigger bill. We confirm the fault, fix the root, and verify the whole system holds air and stops straight before the truck leaves. Done right the first time, because brakes don’t get second chances.
PRICING YOU CAN SEE COMING
You’ll hear our hourly rate, our minimum, and any surcharges up front. Mobile road service is billed port to port — from when we leave the shop to when we return — and the price only changes if the job changes. Stranded with locked brakes doesn’t mean a padded bill; you pay our standard rate.
MOBILE OR IN THE SHOP
Plenty of air brake work gets handled on site, and we’ll come to you for it. For bigger jobs, we don’t run tow trucks, but we work with a network of tow companies and get the best rates to bring your truck in and finish the repair here.

A FEW QUICK ANSWERS
Can you come to me for brake work?
Yes — a lot of air brake repair is done roadside or on site. If it needs the shop, we line up the tow at the best rate and finish it there.
My brakes froze overnight — can you help?
Yes. Frozen-brake calls are common here in winter and we handle them safely, then find the moisture source.
Will you tell me if a part doesn’t actually need replacing?
Always. You only pay for the work that’s actually needed.
Brake trouble or locked up in the cold?
Don’t risk it. Call J&A Fleet at (815) 518-5252 for air brake repair done right.
