Frequently Asked Questions
What types of truck brakes do you repair?
We service air brake systems on semi trucks and trailers, including drums, shoes, slack adjusters, brake chambers, S-cams, air lines, valves, and ABS components, plus hydraulic brakes on lighter commercial vehicles.
How do I know my semi needs brake service?
Watch for longer stopping distances, grabbing or pulling to one side, air pressure warning buzzers, squealing or grinding, a spongy pedal, or excessive slack. If you notice any of these, call 717-865-2388 before your next load.
Do you replace air brake chambers and slack adjusters?
Yes. We replace brake chambers, automatic and manual slack adjusters, S-cams, bushings, and drums, and we set proper pushrod stroke so your brakes pass DOT inspection.
Can you diagnose ABS faults and warning lights?
Yes. We read ABS fault codes with professional diagnostic software, test wheel-speed sensors and modulator valves, and repair the wiring or components causing the light.
Will my truck pass DOT inspection after a brake job?
We repair brakes to FMCSA out-of-service standards, and as a PA inspection station we can verify pushrod stroke, lining thickness, and air system performance so your truck is compliant.
Do you offer mobile or emergency brake repair?
Yes. Our mobile mechanics handle brake emergencies 24/7 along I-81, I-78, I-76, I-83, and nearby routes in Central Pennsylvania. Call 717-865-2388 if you are stranded with a brake problem.
How long does a brake job take?
A standard axle brake replacement is often completed the same day, while full air system repairs depend on parts and the extent of wear. We give you a time estimate after inspecting the brakes.
What payment methods do you accept?
We accept EFS, T-Chek, ComData, WEX, Fleet One, all major credit cards, and cash.
