Key Features & Benefits

This compressor basically takes engine power and turns it into compressed air. It pumps air into your vehicle’s air brake system – think of it like the heart of that system. It builds up pressure and maintains it, ready to go when you need those brakes. It also handles things like the air suspension, if your vehicle has that, and even powers other air – operated accessories. The compressor is a key part of your air brake system. It’s what makes everything work – your brakes aren't going to engage without that consistent air pressure. It constantly runs when the engine is on, keeping the system topped up. It's not a part you directly control, it just works in the background.

Symptoms, Risks & Replacements

Well, think about it…your brakes are pretty important, right? Without a working compressor, you’ll lose air pressure, and you’ll notice if that happens pretty quickly – your brake pedal will go soft, and stopping becomes…difficult. It's a safety thing, first and foremost. A failing compressor means failing brakes. It’s definitely something you want to address as soon as you suspect there’s a problem. We carry a good selection of these at Fixparts Online, and getting a new one installed is a lot cheaper than dealing with brake failure. It’s a preventative maintenance item that saves a lot of headache down the road.
