Brake System Repair
Air leaks, locked brakes, worn shoes and drums, chambers and lines.
Can truck air brakes be repaired on the roadside?
Yes, in most cases. Diesel Rx repairs air brake problems on site, including air leaks, damaged lines and hoses, brake chambers, slack adjusters and worn shoes or drums. We work on diesel trucks of all makes and models, and we are available 24/7 across Upstate South Carolina and nearby North Carolina.
When to call us
- Audible air leak or air pressure that will not build
- Brakes locked up and will not release
- Low air warning light or buzzer
- Pulling to one side under braking
- Grinding, squealing or a burning smell
- Brake violations written up at inspection
How the job goes
Locate the fault
We check the air system, chambers, lines and foundation brakes.
Replace what failed
Lines, fittings, chambers, slack adjusters, shoes and drums as needed.
Adjust and test
We confirm pressure builds, brakes apply and brakes release.
Back on the road
You leave with brakes that work, not a temporary patch.
Good to know
Brake problems are safety problems. If the truck is not safe to move, do not move it. Call us and we will come to you.
