Key Features & Benefits

This cylinder is part of your braking system, specifically dealing with the application of force to the brake shoes or pads. It takes hydraulic pressure from your master cylinder—basically, when you push the brake pedal—and converts that pressure into a mechanical force that pushes things into action at the wheel. The 35x40 refers to its dimensions – that tells us the size and what vehicles it’s designed to fit. It's a pretty simple component, honestly. It pushes, that's it. It’s a slave cylinder, which means it receives instructions from the master cylinder. Think of your master cylinder as the brain sending a message, and this cylinder as the muscle that actually does the work. It's usually found at each wheel, and it’s a critical piece in getting your brakes to engage. It pushes on the brake shoes or pads to create friction against the brake rotor or drum, and that’s what stops the car.

Symptoms, Risks & Replacements

Well, if this fails, your brakes won't work properly at that wheel. That’s obviously a big deal. You’ll notice if one isn’t working correctly – pulling to one side when you brake is a common sign, or maybe a spongy brake pedal. It acts like a shield between the hydraulic pressure and the mechanical action at the wheel. Over time these cylinders can develop leaks or the internal parts can wear out, so it’s something you definitely want to keep an eye on. If you’re doing brake work, it’s a smart idea to replace these at the same time as the master cylinder and brake lines.
