This part basically takes the hydraulic pressure from your master cylinder – that’s what you push when you press the brake pedal – and turns it into mechanical force. Inside each wheel cylinder are pistons, and those pistons push out against the brake shoes, pressing them against the brake drum. It’s how your brakes actually work at each wheel. It’s a core component of your drum brake system, specifically. Each wheel that uses drum brakes will have a wheel cylinder. It’s located right at the wheel, inside the back plate of the brake assembly. You’ll find them on older vehicles, and sometimes still on the rear of some newer cars and trucks. It works alongside the brake shoes, springs, and drum itself to stop the vehicle. Well, if it starts to leak, or one of the pistons gets stuck, your brakes lose power at that wheel. You’ll notice if your brake pedal feels spongy, or if the car pulls to one side when you brake. A really bad leak will obviously mean significantly reduced stopping power, which is a serious safety concern. They're pretty straightforward parts, but crucial. If you’re doing brake work, it’s a good idea to replace these along with the brake shoes and hardware. Fixparts Online carries a good selection of these, and they can be a real pain to mess with once they're corroded, so it's often worth doing it proactively.
