Wabco 4214420170 Piston Cylinder

Description

The Wabco 4214420170 Piston Operating Cylinder is a critical component within brake control systems, specifically acting as a slave cylinder. It's designed to convert hydraulic pressure into mechanical force to actuate brake components. This cylinder is used in applications requiring precise and reliable braking performance. Its double-acting design, with a 35.0 mm piston diameter and 40.0 mm stroke, delivers a piston force of 520 N. The cylinder features M12 x 1.5 inlet and port threads, an M8 push-rod thread, and mounting via a Ball socket B10 DIN 71805. With dimensions of 40 x 45 x 178 mm and a total length of 168.0 mm, it operates effectively within a temperature range of -30°C to +80°C, ensuring consistent performance. This OE specification cylinder provides enhanced braking responsiveness and reliability.

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.
