Wabco 4613150770 Foot Brake Valve

Description

The Wabco 4613150770 Foot Brake Valve is a critical component in air brake systems, primarily used in commercial vehicles and trailers to control the braking function via a foot pedal. This valve regulates air pressure to the brake actuators, enabling effective and reliable stopping power. It features a robust design with port threads of M16 x 1.5 and M12 x 1.5, and operates within a temperature range of -40°C to +80°C. The valve's dimensions are 93 x 83 x 155 mm, and it meets OE specifications for performance and durability. Its calculated volume is 1.1964 and the distance between mounting holes is 61x61 mm.

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.
