The System You Cannot Compromise
Air Brake Repair Done to Inspection Standard
Air brakes are the one system on a truck where a shortcut is genuinely dangerous. They are also the system that most often puts a vehicle out of service at the roadside, because leaks and adjustment problems develop gradually and drivers stop noticing the compressor cycling more often than it used to.
We trace leaks properly, replace what is damaged rather than patching it, and set adjustment to specification. On a loaded truck coming down a grade, that is not detail work. It is the whole point.
- Air leak tracing
- Line and fitting replacement
- Brake chamber service
- Slack adjuster work
- Governor and compressor faults

- Gladhand and seal repair
- Pre-inspection brake checks
Air System Symptoms
Air Brake Faults You Should Not Drive On
Several of these are out-of-service items the moment an inspector sees them.
-
Compressor cycling far more often
The system is losing air somewhere and working harder to keep up with it.
-
Audible hiss when parked
A leak you can hear is a leak an inspector will find in about ten seconds.
-
Long pressure build at start-up
A tired compressor or a leak that has been getting worse for weeks.
-
Brakes grabbing unevenly
Adjustment differences between wheels, which upsets braking under load.
-
Water blowing from the tanks
The air dryer has stopped working, and moisture in the lines freezes in winter.
Air System Method
How We Work an Air Brake Problem
Find every leak, not just the loudest one.
-
Build and Hold
Charge the system fully and measure how quickly it actually drops.
-
Trace by Ear and Soap
Every fitting, chamber and line checked rather than stopping at the first.
-
Replace, Not Patch
Damaged lines and seals are renewed properly on safety-critical circuits.
-
Reverify Under Pressure
The system is retested and adjustment confirmed before you move off.

Air Brake Questions
Questions About Air System Repair
The system has lost enough pressure that the spring brakes have applied, which is exactly what they are designed to do. It is a safety feature, not a malfunction. Something is leaking, and the truck stays put until it is found.
