This little guy takes the hydraulic pressure from your master cylinder – that’s what you push when you hit the brake pedal – and turns it into the mechanical force that actually pushes your brake shoes out against the brake drum, or your brake pads against the rotor if you have disc brakes. Basically, it's a hydraulic actuator. It receives fluid pressure and converts it into stopping power at each wheel. Each wheel has one of these, or a comparable component in a disc brake system. They work in unison with everything else in your braking system. The master cylinder sends pressure down the lines, and these cylinders at the wheels are the last stop before the actual braking happens. They're part of what makes your brakes “bite”. If one of these fails, that wheel won’t brake properly, or might not brake at all. That causes a huge imbalance in your stopping power. You’ll notice if one is failing because the car will pull to one side when you brake, or you might get a spongy brake pedal. It’s a safety thing, plain and simple. You really don’t want to mess around with bad brake components. If you're doing brake work yourself, Fixparts Online has a good selection of these, but a mechanic can definitely diagnose if you need to replace it and do the work for you. Our promise to you: Wheel Brake Cylinder (MPN BWD226) comes with a 12-month warranty!
