Wabco 9254070030 Spring Brake Cylinder

Description

The Wabco 9254070030 Spring Brake Cylinder 24 is a critical component within air brake systems, specifically designed to convert air pressure into mechanical force to activate the vehicle's brakes. It is commonly used in heavy-duty trucks, buses, and trailers to ensure reliable and efficient braking performance. This cylinder features a robust design with a nominal diameter of 8.5 mm and a stroke of 65.0 mm, capable of delivering an output force of 10000 N at a maximum operating pressure of 10.0 bar. Its air-cooled operation and OE specification ensure durability and compatibility, while dimensions of 193 x 187 x 356 mm allow for seamless integration into existing systems. The cylinder operates using a cam mechanism and features M16 x 1.5 threads for both bolt connections and port threads.

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.
