The total length of this midskirt is 1.4 meters, and its OE specification ensures optimal performance and compatibility within the air brake system.

Key Features & Benefits

Basically, the mid skirt is a component of your trailer's air brake chamber. It’s a flexible diaphragm – think of it like a sturdy rubber sheet – that moves back and forth inside the chamber when air pressure changes. It’s what actually pushes on the brake shoes or pads to get the trailer to stop. It responds to signals from your brake pedal and translates that into mechanical force. It’s also sealed, so it helps maintain the air pressure inside the chamber. It’s a key part of how your trailer’s brakes work. When you hit the brakes in your truck, air is sent through the lines to these chambers on the trailer. The mid skirt inside responds to that air pressure and pushes on the internal mechanisms to apply the brakes. Without a good mid skirt, you lose that force, and your trailer won't stop properly. It's really the heart of the chamber's function.

Symptoms, Risks & Replacements

Well, if this thing fails, your trailer brakes won't work reliably, plain and simple. It acts like a shield, keeping the internal components sealed and protected, but it does wear out over time with constant flexing. You’ll notice if it’s failing because you might get longer stopping distances, or the brakes might feel spongy. It's a safety critical part, so it’s something you want to keep an eye on. You can find replacements pretty easily—we stock a lot of them, and places like Fixparts Online are good for finding what you need for your specific trailer. A failing mid skirt isn’t something you want to mess around with, it affects everything when you’re hauling.
