Why fleets and drivers choose T&T
We measure
Slack travel, drum out-of-spec, lining thickness, push-rod travel. Numbers go on the inspection sheet. You see the data, not just 'brakes are fine.'
Air system leak hunting with the right tools
Slow leaks are how brakes go from fine to out-of-service overnight. We pressure-test, sonic-detect, and find the culprit instead of replacing parts and hoping.
Per-axle brake job records
Documented work per axle, per unit. Useful for warranty disputes, pre-trip evidence, and predicting when the next axle is coming due.

Frequently asked
- How do I know if my brakes are out of adjustment?
- Excessive push-rod travel at brake application is the textbook sign. Drivers describe it as a 'softer' or 'longer' pedal, brake fade on a long descent, or pulling to one side. The DOT measure is straightforward — over the limit and you're out of service.
- Can you diagnose a slow air leak?
- Yes. Slow air leaks are usually a fitting, a chamber diaphragm, an air dryer governor, or a leaky valve. Sonic leak detection finds them in a fraction of the time soap-and-water takes.
- How long does a brake job take?
- Per axle, drum brakes: typically half a day if you have the truck in by morning. Full-truck brake job (all axles): 1–2 days depending on parts. Air-disc work runs longer because of caliper and rotor R&I.
- Do you do brake jobs on trailers too?
- Yes — trailer brake work is one of our most common jobs. Same shop, same techs, same documentation.
- What's the difference between drum and disc for our fleet?
- Drum is cheaper to maintain and repair, longer lining life. Disc has better stopping performance, less fade, faster service times. Most heavy-duty fleets are mixed. We work on both — we'll tell you what makes sense for the truck and the work it does.
