Wabco 9255919600 Spring Brake Cylinder

Description

The Wabco 9255919600 Spring Brake Cylinder is a critical component within air brake systems, responsible for applying the spring brakes in commercial vehicles. It's used in the air brake systems of trucks, trailers, and buses to provide a fail-safe braking mechanism. This cylinder ensures reliable emergency braking and parking functionality, enhancing overall vehicle safety and control. Its dimensions are 185 x 200 x 296 mm, and it adheres to OE specifications for dependable performance.

Key Features & Benefits

Basically, this cylinder converts air pressure into mechanical force. It pushes a rod out when air is applied, and that rod is what actually activates the brakes – specifically the spring brakes on your vehicle. It also holds those brakes in when the air pressure is released, using an internal spring. It’s a bit like a muscle, flexing and retracting with air pressure. Think of it as a key part of your safety system. It's primarily used with spring brakes, which are a fail – safe. These brakes automatically engage if you lose air pressure – say, a leak in the system or if the engine quits. So this cylinder controls when those spring brakes stay released during normal driving, and when they need to apply if something goes wrong. You'll find them mainly on heavier vehicles - trucks, trailers, buses - anything where a runaway situation would be especially dangerous.

Symptoms, Risks & Replacements

It’s super important because it’s a critical part of that fail – safe system. If this cylinder fails, your spring brakes might not release properly when you want them to, or they might not apply when you need them to. You’ll notice if it's failing – things like brakes dragging, difficulty releasing brakes, or even the brakes applying themselves unexpectedly. A faulty spring brake cylinder can really affect stopping distance and vehicle control. We carry a good selection of these at Fixparts Online, and we always recommend replacing these in pairs – if one goes, the other is likely not far behind.
