Key Features & Benefits

A midskirt is basically a flexible connection piece that sits between sections of air brake lines on a trailer – usually connecting the main air line to the spring brake chambers. It allows for movement and flex without putting stress on the rigid air lines and connections. It distributes the air signal down the length of the trailer. It’s designed to handle vibration and the general jostling a trailer gets while it’s moving. Think of it as a kind of central nervous system for your trailer brakes. It receives the signal from your tractor protection valve – when you hit the brakes in your truck – and sends that signal to each of the wheel brakes. It’s essential for making sure all the brakes engage evenly and reliably. It bridges the gap and takes up some of the motion, so the rigid lines don’t crack or fail.

Symptoms, Risks & Replacements

It's important because if it fails, your trailer brakes may not function properly. You’ll notice if it's leaking air, obviously, because you’ll have reduced braking power and a sag in the trailer. A cracked or damaged midskirt can cause inconsistent brake application, which is dangerous. It acts like a shield, preventing stress fractures in your main air lines. It’s a relatively inexpensive part, and honestly, it's a good idea to replace it during preventative maintenance. You can find them pretty easily – Fixparts Online has a good selection, for example. Better to replace it now than deal with a brake failure later.
