Wabco 9254321210 Tristop Cylinder

Description

The Wabco 9254321210 Tristop Cylinder is a crucial component within air brake systems, specifically functioning as a brake actuator. It's designed for use in heavy-duty vehicles and trailers where reliable and responsive braking performance is essential. This cylinder converts air pressure into a mechanical force, enabling the activation of the vehicle's brakes. With a stroke of 65/65 mm and dimensions including a distance between bolts of 120.6 mm, bolt lengths of 42.0 mm with M16 x 1.5 threads, and 16 mm clevis pins, this cylinder offers precise control and durability. Operating within a maximum pressure of 8.5 bar and a release pressure of 4.9 bar, it provides consistent and powerful braking, with an output force of 10600 N. The return-spring force of 440 N ensures quick response and reliable operation, all while meeting OE specifications.

Key Features & Benefits

This little guy basically controls the air brakes on your trailer – it manages the air pressure to the spring brakes. It has three positions – that’s where the “Tri” comes from – allowing it to apply, hold, and release the trailer brakes. It's essentially a valve that directs airflow, deciding when the brakes engage and disengage. It also releases air pressure when you need to free up the brakes. Think of it as a key component in your trailer’s safety system. It’s located within the brake actuator, which is how your truck’s signal to stop translates into actual braking power on the trailer. Without it functioning properly, the trailer might not respond when you hit the brakes, or it might lock up unexpectedly. It's the connection between what you do in the cab and what happens with the trailer wheels.

Symptoms, Risks & Replacements

It’s critically important because it’s a direct safety component. If it fails, you lose control over your trailer brakes, which is a really dangerous situation. You’ll notice if it’s going bad – things like the trailer brakes dragging, not fully releasing, or feeling spongy when you apply the pedal. It’s a relatively inexpensive part when you consider what it protects. We carry them at Fixparts Online, and it’s something you really want to address promptly if you suspect a problem. Ignoring it can lead to much bigger and more expensive repairs, and more importantly, a potential accident.
