Wabco 4214100390 Piston Cylinder

Description

The Wabco 4214100390 Piston Operating Cylinder is a crucial component within brake control systems. It's specifically designed for use in applications requiring precise linear actuation, converting hydraulic or pneumatic pressure into mechanical force. This cylinder is commonly found in braking systems where reliable and responsive operation is paramount. The cylinder boasts a 30.0 mm piston diameter and a stroke of 25.0 mm, providing a piston force of 300 N. Its dimensions are 40 x 40 x 127 mm. With a calculated volume of 0.2032 and a maximum operating pressure of 10.0 bar, this single-acting cylinder delivers consistent performance across a temperature range of -40°C to +80°C. The OE specification ensures compatibility and reliability, while features like M10x1 inlet and port threads, alongside a Ø 6 mm mounting point, contribute to ease of installation and integration.

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.
