Wabco 4214113090 Piston Cylinder

Description

The Wabco 4214113090 Piston Cylinder is a crucial component within brake control systems, specifically functioning as a slave cylinder. It's designed to convert hydraulic pressure into mechanical force, enabling the actuation of brake calipers or other braking mechanisms. This cylinder is commonly used in various braking applications requiring precise and reliable performance. This single-acting cylinder boasts a piston diameter of 35.0 mm and a stroke of 54.0 mm, operating efficiently within a temperature range of -25°C to +120°C. With a calculated volume of 0.41904 and a maximum operating pressure of 10.0 bar, this device delivers a substantial output force of 420 N. Its dimensions are 48 x 45 x 194 mm, and it features connections including 1/4 - 18 NPTF and M12 x 1.5 port threads, ensuring compatibility with existing systems. The cylinder's OE specification and robust construction provide enhanced durability and consistent performance, optimizing braking responsiveness and safety.

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.
