It's designed to convert hydraulic pressure into mechanical force to actuate brake components. This single-acting cylinder features a piston diameter of 35.0 mm and a stroke of 85.0 mm, delivering a piston force of 420 N. Its dimensions are 272 x 35 x 35 mm, and it incorporates M12 x 1.5 port threads, along with an M12x1.5 inlet port and a push-rod thread of ø8 H11. Manufactured to OE specification, this cylinder offers precise and reliable brake actuation, ensuring consistent performance and durability within demanding applications. The calculated volume is 0.341 and it can operate within a temperature range of -40°C to +80°C.

Key Features & Benefits

This part basically takes the fluid pressure from your master cylinder – when you push the brake pedal – and turns it into mechanical force. Inside, there’s a piston that moves when hydraulic pressure comes in, and that movement pushes on the brake shoes or pads, making them press against the brake drum or rotor. It's really just a hydraulic amplifier, taking a little foot pressure and turning it into a lot of stopping power at each wheel. It’s a critical part of your braking system, naturally. It lives at each wheel, and you'll have one for each brake. So, if you’re working on the rear brakes, which often use wheel cylinders to actuate the shoes, this is what you’re dealing with. It receives the signal from when you hit the pedal and does the actual work of squeezing the brakes.

Symptoms, Risks & Replacements

Well, without it, you wouldn’t be able to stop. If it fails, you'll notice if you're having trouble stopping – it might feel spongy, or the car might pull to one side. A leak in the cylinder means you’re losing brake fluid, and losing braking power, obviously. It essentially acts like a shield, protecting your ability to slow down and stay safe. You can find these pretty easily online, even places like Fixparts Online have a good selection. Replacing a worn cylinder is a straightforward repair, but definitely important to keep your brakes working correctly.
