Wabco 4214100720 Piston Cylinder

Description

The Wabco 4214100720 Piston Cylinder is a crucial component within a vehicle's brake system, specifically functioning as a slave cylinder within the brake controls. It's designed to convert hydraulic pressure into mechanical force, enabling the actuation of brake calipers and ultimately stopping the vehicle. This cylinder features a 35.0 mm diameter and a 30.0 mm piston diameter, delivering a piston force of 300 N with a stroke of 25.0 mm. Its dimensions are 42 x 40 x 117 mm. Engineered to OE specification, this single-acting cylinder provides reliable performance across a temperature range of -20°C to +80°C and operates effectively up to a maximum pressure of 8.0 bar. The inclusion of M10x1 inlet and port threads, alongside a Ø 6 mm mounting configuration, ensures compatibility and secure installation.

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.
