Wabco 12-140-013 Wheel Cylinder

Description

The Wabco 12-140-013 Wheel Cylinder is a vital component of hydraulic brake systems, responsible for converting hydraulic pressure into the mechanical force needed to press the brake shoes against the brake drums. This cylinder is commonly used in braking systems for trailers and light-duty commercial vehicles. This robust design ensures consistent braking performance and increased safety, delivering reliable operation and minimizing downtime through its durable construction.

Key Features & Benefits

These things basically take the hydraulic pressure from your master cylinder – that’s what you push when you hit the brake pedal – and turn it into mechanical force. Inside each cylinder there are pistons. When pressure comes in, those pistons push out against the brake shoes, pressing them against the brake drum. That’s what actually slows the car down. Each wheel usually has its own cylinder, or sometimes they’re paired together. Think of it as part of the team that makes your brakes work. The master cylinder is the commander, sending the order to stop, and the wheel cylinder is one of the soldiers actually doing the work at each wheel. It's located inside the brake drum, right where the brake shoes are. It's a pretty simple part, honestly, but absolutely critical.

Symptoms, Risks & Replacements

Because if this thing fails, you lose braking power at that wheel. That can pull your car to one side when you brake, make stopping distances way longer, or even cause complete brake failure at that wheel. You'll notice if one goes bad – usually a soft or spongy brake pedal, or pulling to one side while braking. Leaks are another big sign, you'll likely see brake fluid around the wheel. They’re wear items, so they do eventually need replacing. You can find these pretty easily, even on a site like Fixparts Online if you want to check prices and availability. But yeah, definitely important to keep in good shape!
