Wabco 9253840100 Double Diaphragm Tristop 16/24

Description

The Wabco 9253840100 Double Diaphragm Tristop 16/24 is a crucial component within air brake systems, specifically functioning as a brake actuator. It is designed for use in heavy-duty vehicle applications, ensuring reliable and efficient braking performance. This device operates as a disc brake actuator, converting air pressure into mechanical force to engage the brakes. The Tristop design incorporates a fail-safe mechanism, enhancing overall system safety and dependability. With dimensions of 190 x 220 x 370 mm, this actuator delivers outputs of 6500 N and 8600 N, operating within a temperature range of -40°C to +80°C, and features a stroke of 57/57 mm. Its robust construction and precise engineering contribute to extended service life and reduced maintenance requirements.

Key Features & Benefits

This part is basically the heart of your trailer’s air brake system’s service application. It converts the air pressure from your tow vehicle into the mechanical force that actually applies the trailer brakes. Specifically, it’s a spring brake actuator, meaning it has a spring emergency system built in. It has two diaphragms working together, and that "Tristop" part means it's got three stages of braking – service, emergency, and parking. It regulates the air pressure so you get smooth, controlled braking, but also automatically engages the brakes if you lose air pressure, which is a huge safety feature. Think of it as the muscle for your trailer brakes. Your foot on the brake pedal in the truck creates air pressure, and this actuator takes that air and turns it into the force that pushes the brake shoes or pads against the drums or rotors on the trailer. It’s mounted directly to the trailer’s brake chamber, and is crucial for controlled stopping. It’s part of the air brake system, so it works with the air compressor, air lines, and the brake chambers themselves.

Symptoms, Risks & Replacements

It’s incredibly important for safety, plain and simple. If this fails, you lose braking ability on your trailer. The spring brake feature will engage if you lose air, acting like a shield against runaways, but you want this part working correctly before it gets to that point. You’ll notice if it’s starting to go bad – things like longer stopping distances, or brakes that aren’t releasing fully. It’s really a critical component, and it's worth getting a good quality one. We have a good selection of these at Fixparts Online, and you can usually find diagrams and helpful info there too. It’s definitely a part you don't want to skimp on when it comes to maintenance.
