Wabco 4214100250 Piston Cylinder

Description

The Wabco 4214100250 Piston Operating Cylinder is a critical component within brake control systems, specifically functioning as a slave cylinder. It's designed to convert hydraulic pressure into mechanical force, enabling the activation of brake calipers or other braking mechanisms in commercial vehicles. This single-acting cylinder features a 30.0 mm piston diameter and operates within a temperature range of -40°C to +80°C, ensuring reliable performance in diverse conditions. Its dimensions are 43 x 42 x 117 mm, and it includes M10x1 inlet and port threads. The cylinder's OE specification ensures compatibility and consistent braking performance, while its robust construction delivers durability and long service life.

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.
