Description

The Wabco 9253205310 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 to facilitate the conversion of air pressure into mechanical force, enabling effective braking. This cylinder features a cam-operated design and is of the 20/30 type, complete with a protective boot. Key dimensions include a total length of 284.0 mm, a stroke of 57/57 mm, and a push-rod length of 60 mm. It features M16 x 1.5 port threads and accepts 33.0 mm bolts with M16 x 1.5 threads, secured with 14 mm clevis pins, spaced 120.6 mm apart. Operating within a temperature range of -40°C to +80°C, this cylinder provides reliable performance up to a maximum operating pressure of 10.0/10.0 bar, delivering output forces of 11200 N and 7000 N, and features a return-spring force of 250 N. It’s built to OE specification, ensuring compatibility and consistent braking performance.

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.
