Wabco 9253751000 Tristop Cylinder 20/30

Description

The Wabco Tristop-Cylinder 20/30 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 to convert air pressure into mechanical force, enabling effective braking. This cylinder boasts a robust design with dimensions of 205 x 205 x 473 mm and utilizes a cam-based operation. The Tristop-Cylinder 20/30 provides precise and reliable braking performance, contributing to enhanced safety and control. Its OE specification ensures compatibility and consistent functionality. The cylinder features M16 x 1.5 port and bolt threads, a 75/75 mm stroke, and a maximum operating pressure of 10.2/8.5 bar, delivering a substantial output force of 7000 N to 7500 N.

Key Features & Benefits

This little guy is essentially a pressure regulator for your trailer’s air brakes. It takes the air pressure from your towing vehicle and splits it into two separate lines – one for the service brakes, which are your normal stopping brakes, and one for the spring brakes, which are usually a parking or emergency brake. It precisely controls how much air goes to each system. It's designed to prioritize the service brakes first, giving you reliable stopping power, and then it feeds the spring brakes. It's a pretty smart piece of engineering, actually. Think of it as the traffic controller for your air brake system. It ensures the right amount of pressure is going where it needs to go when it needs to go there. It sits within your air brake actuator setup, and receives air from the tractor protection valve. It’s a key component in a trailer air brake system. Without this functioning correctly, you won't have consistent or reliable brake performance, and that's…well, you can imagine.

Symptoms, Risks & Replacements

This is really important for safety. If this cylinder fails, you could end up with weak service brakes, or the spring brakes applying unexpectedly, or even both. You’ll notice if it's going bad; you might get inconsistent braking, or the trailer brakes might drag. It acts like a shield, protecting your service brakes and ensuring they respond quickly when you hit the pedal. You can find these fairly easily, we often stock them at Fixparts Online, but more importantly, getting a good one and making sure it's installed correctly is vital. It's not a part you want to gamble on.
