Wabco 9253228017 Tristop Cam Cylinder

Description

The Wabco 9253228017 Tristop Cam Cylinder is a critical component within air brake systems, specifically functioning as a brake actuator. It's designed for use in heavy-duty vehicles and trailers, converting air pressure into mechanical force to engage the brakes. This cylinder features a cam-based operation and is identified as Type 27/16. Its dimensions are 240 x 420 x 260 mm. The cylinder offers precise and reliable braking performance through its robust design and adherence to OE specifications, ensuring consistent operation across a temperature range of -40°C to +80°C. It’s designed for a maximum operating pressure of 10.2/8.5 bar and delivers an output force of 6200 N with a stroke of 57/57 mm.

Key Features & Benefits

This little guy basically takes the air pressure from your brake system and turns it into mechanical motion. It pushes on the brake shoes – or pads, depending on your setup – to make your brakes work. It’s got three distinct stopping positions, hence the “Tristop” name. Those positions give you different levels of braking force – a light touch for holding, a medium one for normal stopping, and then full force for emergencies or really steep hills. It’s a pretty clever system when it works right. It's a key part of your air brake actuator, which is the whole assembly that actually does the braking. Air brakes, unlike hydraulic brakes in a lot of cars, rely on compressed air to work. The air comes in, pressurizes the cylinder, and this component converts that air pressure into the force needed to slow or stop the vehicle. It's most common on larger vehicles – trucks, buses, trailers – things that need serious stopping power.

Symptoms, Risks & Replacements

Well, obviously brakes are pretty important, right? But this particular part is crucial for smooth, controlled braking. If it starts to leak air, or gets stuck, you’ll notice if your brakes feel spongy or grabby, or if your parking brake doesn’t hold like it should. It affects your stopping distance, and more importantly, your control. A failing cylinder can really compromise safety. You can find these fairly easily online; we stock them at Fixparts Online, but a lot of places do. You’ll want to replace it if it’s leaking or if the brakes aren’t functioning properly. Think of it like a shield protecting your ability to stop—if the shield gets damaged, you’re vulnerable.
