Air Brake Repairin Ontario, CA.

An audible air leak, pressure that builds slowly or drops quickly, the low air warning coming on, the truck pulling to one side when braking, long stopping distances and grinding or squealing are common signs. Air brake problems should be checked right away.

A worn air compressor, a leaking governor, a clogged or failed air dryer, or leaks in lines, fittings, valves or tanks can all slow pressure build. We leak test the system to find the cause.

It keeps the brake shoes at the correct distance from the drum so the brakes apply fully. Automatic slack adjusters that keep going out of adjustment usually point to a worn part in the brake that needs repair, not just readjustment.

Yes. Brakes out of adjustment, air leaks, worn linings and cracked drums are among the most common reasons trucks are placed out of service. Fixing them before an inspection keeps your truck on the road.

Check them at every preventative maintenance service and any time you notice a change in braking. Heavy hauling and stop and go routes wear brakes faster.

We work on light, medium and heavy duty diesel trucks, fleet vehicles, trailers and RVs, including Freightliner, International, Peterbilt, Kenworth, Volvo, Mack, Hino, Isuzu, Ford Power Stroke, Ram Cummins and GM Duramax.

It depends on the truck, the parts and what we find. We diagnose first, then explain the repair options and the price before any work begins, so there are no surprises. Call, text or use the form to get started.

Calling ahead is best so we can plan bay time and parts. If your truck is down, call (909) 701-8755 and we will tell you the fastest way to get it in.
