Wabco 4214100520 Piston Cylinder

Description

The Wabco 4214100520 Piston Operating Cylinder is a critical component within brake control systems, specifically functioning as a slave cylinder to transmit hydraulic pressure from the master cylinder to the brake calipers. It's designed for use in pneumatic brake systems, converting air pressure into mechanical force to actuate the brakes. Measuring 43 x 50 x 119 mm, this single-acting cylinder boasts a piston diameter of 30.0 mm and delivers a piston force of 300 N. It features an M6 female mounting point, accepts a hose connection of 5x3, and operates effectively within a temperature range of -40°C to +80°C. With a calculated volume of 0.25585 and a stroke length of 25.0 mm, this cylinder ensures precise and reliable brake actuation, meeting OE specifications for optimal performance and durability.

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.
