Wabco 9730110032 Repair Kit

Description

This Wabco 9730110032 Repair Kit is designed for use in air brake systems, specifically with relay valves. It provides a complete set of components to restore the functionality of the relay valve, ensuring consistent and reliable braking performance. This kit adheres to OE specifications, guaranteeing compatibility and ease of installation. The dimensions of the repair kit are 68 x 81 x 98 mm.

Key Features & Benefits

This kit essentially rebuilds the relay valve. The valve itself takes a low – pressure signal from your cab – when you push the brake pedal – and boosts it up to a higher pressure to actually apply the brakes on the trailer. The kit includes new seals, diaphragms, maybe some o – rings – anything that tends to wear out inside the valve over time. It doesn’t replace the whole valve housing, just refreshes the working parts. Think of it as a crucial link in your air brake system. You press the pedal, this valve amplifies that signal, and then your trailer brakes get activated. It’s specifically for trailers with air brakes – you won’t find this on a passenger car. It's part of what keeps everything safe and responsive when you need to slow down or stop a loaded trailer.

Symptoms, Risks & Replacements

Well, if this valve starts to leak or doesn’t hold pressure correctly, your trailer brakes will become weak or unresponsive. You’ll notice if your trailer is taking longer to stop, or you might feel a “mushy” brake pedal. A failing relay valve acts like a shield that’s cracked – it still tries to protect you, but it’s not doing the job fully. Replacing the seals and parts in this kit gets everything working correctly again, ensuring you have full braking power when you need it. You can find these kits pretty readily, and Fixparts Online carries a good range of them if you're looking. It’s a relatively straightforward repair, but it's definitely something you want to address promptly for safety’s sake.
