Wabco 4214250110 Piston Cylinder

Description

The Wabco 4214250110 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 operation of brake calipers or other braking mechanisms. This cylinder is typically found in commercial vehicle braking systems. Engineered to OE specification, this single-acting cylinder provides precise and reliable brake actuation. Its dimensions are 30 x 164 x 40 mm, with a piston diameter of 25.0 mm and a stroke of 48.0 mm. The cylinder operates effectively within a temperature range of -25°C to +120°C and features M12 x 1.5 port threads, an M8 push-rod thread, and is compatible with a pipe diameter of 6 mm according to DIN 3901.

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.
