Description

This Wabco push-button is a critical component within trailer brake control systems, specifically for air brake applications. It’s designed for use in commercial vehicles and trailers where reliable and responsive braking is essential. This push-button meets OE specification, ensuring optimal performance and compatibility.

Key Features & Benefits

This little button essentially tells your trailer brakes when to apply, and how much. It sends an electrical signal to the trailer brake controller, which then activates the electromagnets in the trailer brakes themselves. Different controllers will use it differently, but generally, the more you push the button, the stronger the signal, and the harder the trailer brakes work. Some controllers use a momentary push for a quick tap of the brakes, while others let you “lock” it in for continuous braking. It's a key part of keeping everything safe when you’re towing. Think of it as the direct link between you and being able to control the trailer’s stopping power. It works with your vehicle’s brakes, but gives you independent control over the trailer. Without it, you’d have a very hard time slowing or stopping smoothly and safely, especially with a heavier load. It's part of the entire air brake system, so it needs to work correctly to maintain air pressure and function.

Symptoms, Risks & Replacements

It’s vital for safety, plain and simple. If this button fails, you lose the ability to properly control your trailer’s brakes. You’ll notice if it’s going bad because the brakes might feel sluggish, unresponsive, or even apply unexpectedly. It’s not something you want to mess around with. You can find these pretty easily, we carry a bunch here and also have a good selection at Fixparts Online if you prefer to look around there. Replacing it is usually pretty straightforward, but if you're not comfortable doing it yourself, definitely have a professional take a look.
