Description

This Wabco repair kit (MPN: 4700159032) is designed for use in trailer brake control systems within air brake systems.

Key Features & Benefits

This kit generally includes things like new seals, o – rings, diaphragms, and maybe even some small check valves. Basically, it has all the little rubber and soft parts inside your trailer brake control unit that tend to wear out over time. It’s designed to rebuild the unit instead of replacing the whole thing. Your trailer brake control unit is the brain of your trailer braking system. It takes the signal from your brake pedal and tells the brakes on your trailer when and how hard to apply. These parts inside aren’t the flashy stuff you see, but they make sure the air pressure is regulated correctly, that the system holds pressure, and that the signals are sent reliably. Think of it as the heart of the system – it has to pump smoothly and consistently.

Symptoms, Risks & Replacements

Well, those rubber parts don’t last forever, especially with temperature changes and constant use. Over time they can crack, dry out, or lose their shape. When that happens, you might get a slow response from your trailer brakes, inconsistent braking power, or even a complete failure. You’ll notice if your trailer feels like it’s pushing you around or takes longer to stop than it should. Ignoring it can be dangerous, plain and simple. A rebuild kit keeps everything sealing properly, maintaining consistent pressure, and acts like a shield against moisture and debris getting into the system. You can often find these kits on sites like Fixparts Online, and it's almost always more cost – effective than replacing the entire control unit if you're handy.
