This valve basically controls the flow of brake fluid within your ABS hydraulic unit. It doesn’t make the pressure, but it directs it. Think of it like a set of rapidly opening and closing gates inside the ABS system. It gets signals from your vehicle’s computer, and based on those signals, it opens or closes to allow or restrict fluid flow to each brake caliper. It’s doing this multiple times a second when your ABS is actively working, or even monitoring things in the background when it isn’t. It's a key component of your anti – lock braking system – ABS. When you slam on the brakes, especially on a slippery surface, the ABS kicks in to prevent your wheels from locking up. This valve is what makes that happen. It rapidly adjusts the brake pressure to each wheel, allowing you to maintain steering control while stopping. It works in concert with the wheel speed sensors and the ABS control module. It’s all connected, but this valve is the muscle doing the fluid control. Well, if this valve fails, your ABS won’t work right. You might get a warning light on your dash, but not always. More likely, the ABS system will either become disabled entirely, or it will function erratically. That means in a hard braking situation, you could lose steering control. It acts like a shield, preventing lockup, so if it’s gone, you’re back to relying on your reflexes alone. You’ll notice if it’s bad usually during hard braking – maybe you'll feel pulsing in the brake pedal that’s more intense than usual, or a complete loss of ABS function. You can find these parts, and a lot of others, over at Fixparts Online, but getting the right one is important. They're usually pretty reliable, but like anything, they can wear out over time, especially with road salt and general use.
