Wabco 9253070080 Spring Brake Cylinder

Description

The Wabco 9253070080 Spring Brake Cylinder 168X67 is a crucial component within air brake systems, designed to convert air pressure into mechanical force to activate the vehicle's brakes. It is commonly used in heavy-duty trucks and trailers to ensure reliable and efficient stopping power. This cylinder operates via a cam mechanism and is constructed to OE specification, providing a direct replacement for original equipment. The cylinder's dimensions are 190 x 270 x 190 mm, and it features M16 x 1.5 bolt threads and a 67.0 mm stroke. Its robust design and precise engineering deliver enhanced braking performance, improved safety, and extended service life, operating effectively within a temperature range of -40°C to +80°C.

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.
