Wabco GA29264 Mini Relay Valve Kit

Description

The Kit-Mini Relay Valve, manufactured by Wabco, is a critical component within air brake systems. It's designed to quickly and reliably distribute compressed air to the service brakes of commercial vehicles, ensuring optimal braking performance. This kit includes all necessary components to replace or rebuild a mini relay valve, commonly used in trucks and trailers. The Wabco MPN for this kit is GA/29264. It measures 30 x 70 x 115 mm. This relay valve enhances system responsiveness, contributes to shorter stopping distances, and ensures consistent brake application, thereby improving overall vehicle safety and control.

Key Features & Benefits

This little kit basically controls the airflow to your air brake chambers. It takes the signal from your brake pedal and rapidly sends a larger volume of air to actually apply the brakes on all axles. It’s got a few different parts inside – usually a valve, some seals, and maybe a filter. It’s all about quick response and consistent pressure. Think of it as the amplifier for your brake signal. When you push the pedal, it doesn’t have enough force on its own to fill all the brake chambers fast enough. The relay valve takes that small signal and boosts it, sending a big rush of air. It’s positioned in the air brake line, usually close to the air compressor and brake chambers. It works with the brake chambers, not instead of them.

Symptoms, Risks & Replacements

It's critical for safe stopping. If this valve is failing, you'll notice if your brakes feel slow to respond, or if one axle isn’t braking as strongly as the others. A leaky valve means you lose air pressure, weakening your braking power. It acts like a shield, protecting your system from delays. Neglecting it can lead to seriously reduced stopping distance, and that’s obviously not good. You can find these kits pretty easily, I often point folks toward Fixparts Online, they have a good selection, but any reputable truck parts supplier will carry them. Just make sure you get the right one for your make and model.
