Wabco 4613180490 Foot Brake Valve

Description

The Foot Brake Valve, manufactured by Wabco (MPN 4613180490), is a critical component in pneumatic braking systems. It's primarily used in heavy-duty vehicles, such as trucks and trailers, to control the air pressure applied to the wheel brakes when the driver presses the brake pedal. This valve precisely regulates braking force, ensuring safe and efficient stopping power. The valve's dimensions are 126 x 258 x 386 mm. It provides responsive and reliable braking performance, enhancing vehicle safety and control.

Key Features & Benefits

This valve essentially controls the air pressure to the rear brakes when you press the foot pedal. It takes the signal from your foot and translates that into the right amount of air going to the brake chambers on the rear axle. It has a couple of key jobs – it regulates how hard the rear brakes apply, and it also makes sure they release properly when you let off the pedal. It’s a proportional control, meaning the more you push, the harder the brakes work, within reason of course. There’s also a “quick release” function built in to help prevent overheating and ensure rapid application. Think of it as the central command for your spring brakes. Your spring brakes are always applied – they’re mechanically on. This valve is what releases them when you want to drive, and applies them more or less firmly when you press the pedal. It’s a critical part of the air brake system, especially for heavier vehicles. It works with the air compressor, the air tanks, and the brake chambers to provide stopping power.

Symptoms, Risks & Replacements

It's important because it directly affects your ability to safely stop the vehicle. If this valve starts to fail, you might notice things like the brakes dragging – meaning they stay partially on even when you aren’t pressing the pedal. Or, you might have weak or inconsistent braking. It's really a safety item. If it completely fails, you can lose braking power to the rear wheels. You’ll notice if the pedal feels spongy or doesn't respond right. It’s one of those things you don't want to mess around with. We carry a lot of these, and you can often find a good selection at places like Fixparts Online, but getting a reliable one is the key.
