Wabco 4613192640 Foot Brake Valve

Description

The Wabco 4613192640 Foot Brake Valve is a critical component within the air brake system of commercial vehicles, responsible for translating a driver's pedal input into braking force. This valve is commonly used in trucks, buses, and trailers to control the air pressure applied to the wheel brakes. It features M22 x 1.5 port threads, a silencer exhaust, and mounts using 4x M8 bolts. Its dimensions are 95 x 109 x 226 mm. The valve operates efficiently with a maximum operating pressure of 10.2 bar and is designed for a temperature range of -40°C to +80°C, ensuring reliable performance in diverse conditions. This OE-specification device delivers precise brake control, enhanced safety, and improved operational efficiency for commercial vehicle applications.

Key Features & Benefits

Basically, this valve translates how hard you press the brake pedal into the amount of air pressure sent to the brakes themselves. It has a couple of main jobs. First, it lets air into the brake system when you push the pedal. Second, it controls how much air goes in—the harder you press, the more air, the stronger the braking. It also has a spring that releases the air when you lift your foot, letting the brakes disengage. It's a pretty simple idea, mechanically, but really critical. This valve is the main link between you and your stopping power in any vehicle with air brakes—think trucks, buses, some larger trailers. When you step on the brake pedal, you're not directly applying the brakes. You’re pushing on a linkage that moves this valve, and that sends the air to the brake chambers at the wheels. Without it, you wouldn't be able to control the brakes at all. It’s a central component of the whole air brake system.

Symptoms, Risks & Replacements

It’s important because, well, brakes are important. This valve directly affects your ability to stop safely. If it starts to leak, or gets stuck, or doesn't respond properly, it can cause weak brakes, or even brakes that drag, overheat, or fail completely. You'll notice if it's failing because you might need to press the pedal much harder to get the same stopping power, or you might feel it not returning to its normal position. It acts like a shield between a good stop and a potentially dangerous situation. We carry a good range of these at Fixparts Online, but you can get them elsewhere, of course. Just make sure you get the right one for your vehicle’s make and model.
