This Repair Kit by Wabco is designed for use in air brake systems, specifically within air valves. It's a crucial component for maintaining the functionality and reliability of commercial vehicle braking systems. This kit adheres to OE specifications, ensuring a precise fit and consistent performance. Measuring 81 x 65 x 99 mm, this repair unit provides a comprehensive solution for valve maintenance and repair. This kit basically rebuilds the protection valve. The valve itself has a couple of jobs. It prevents excessive pressure buildup in your spring brakes, and it also stops air from flowing backwards through the system if there's a leak somewhere. The kit contains new seals, o – rings, maybe a new spring or two – everything you need to refresh the valve instead of replacing the whole unit. Think of it as a safety valve in your braking system. It’s part of what keeps your emergency and parking brakes working reliably, even if your regular air brakes lose pressure. It sits in the air line that feeds those spring brakes. It’s not something you directly control when you hit the brake pedal, it’s there as a backup, a failsafe. Well, if this valve fails, your spring brakes might not hold properly – or worse, they could apply unexpectedly. That’s obviously a big safety issue. Over time, those seals and o – rings just wear out from the air and pressure cycling. You’ll notice if you start having trouble holding on an incline, or if your parking brake isn't as strong as it used to be. Regular maintenance with a kit like this keeps everything working as it should. We carry a lot of these at Fixparts Online, and they're a pretty straightforward repair if you’re comfortable working on your air system. It's a small price to pay for keeping things safe and reliable. Proven by drivers: Repair Kit (MPN 9347059202) is backed by a 12-month warranty!
