Brakes, air and electrical repair
Air leaks, brake problems, charging and wiring faults.
Questions about symptoms
The truck won't build or hold air.
Note how high the pressure gets, whether you hear a leak, and whether the dryer or compressor was recently worked on. That helps us narrow the follow-up questions.
Brakes feel weak or pull to one side.
Tell us whether it happens when the brakes are applied, going down a grade, or at low speed, and whether a warning light or buzzer is on.
The batteries keep going dead, or lights and gauges are acting up.
Electrical faults can be the batteries, charging system or wiring. Note whether it happens after a short sit or overnight, and any recent jump-starts or parts changes.
