Truck Brake Repair in IndianapolisAir leak?Won't release? We stop it.
Mobile heavy-duty air brake service across Indianapolis & central Indiana — shoes, drums, S-cams, ABS, DOT-ready.
Road X provides mobile heavy-duty truck brake repair across Indianapolis and central Indiana, focused on the full air brake system that keeps class 7 and 8 tractors and trailers safe and in service. Our diesel technicians diagnose air leaks, slow air build, governor and dryer faults, then replace shoes, drums, S-cams, slack adjusters and brake chambers on-site — with spring brakes caged and torque specs verified before the wheel goes back on. We handle tractor and trailer ABS diagnostics on Bendix, Haldex, Meritor and WABCO systems, clear wheel speed sensor and modulator codes, and re-inspect the truck to DOT standards so you can lift out-of-service tags and finish the run. If you need a heavy-duty brake mechanic near you, our 24/7 mobile dispatch rolls a fully-stocked service truck to the yard, dock, truck stop or shoulder — no tow, no shop queue.
Serving Indianapolis and surrounding areas including Fishers, Greenwood, Carmel, Plainfield, Avon, Noblesville, and Lawrence.
