Wabco 16923004 Wheel Cylinder

Description

The Wabco 16923004 Wheel Cylinder is a critical component within the brake system of various vehicles. It's located within the brake drum assembly and functions to convert hydraulic pressure into mechanical force, pressing the brake shoes against the drum to facilitate stopping power. This wheel cylinder adheres to OE specifications, ensuring reliable performance and compatibility. Its dimensions are 180 x 278 x 138 mm, contributing to a precise fit and effective braking action.

Key Features & Benefits

Basically, a wheel cylinder takes the fluid pressure from your master cylinder – when you push the brake pedal – and turns it into mechanical motion. Inside each wheel cylinder are pistons, and those pistons push out against the brake shoes, pressing them against the inside of the brake drum. It’s a hydraulic to mechanical conversion, if you want to get technical. So fluid pressure in, pushing force out. Each wheel with drum brakes will have a wheel cylinder. It’s a key component in the drum brake system itself. It works alongside the brake shoes, springs, and the drum itself to actually stop the wheel from turning. It's located right at each wheel, inside the brake assembly.

Symptoms, Risks & Replacements

If a wheel cylinder starts to leak, or if those pistons get stuck, you’ll lose braking force to that wheel. That’s obviously a big safety issue. You’ll notice if one isn't working right, usually because the car will pull to one side when you brake, or the brake pedal will feel soft or spongy. It acts like a shield, protecting you from not stopping when you need to. They’re not super expensive parts, and if you're doing brake work yourself, it’s often smart to replace them in pairs, even if only one is obviously bad.
