Wabco 1811100321 Midskirt 2100 Cut Prim R

Description

The Midskirt 2100 Cut Prim R is a critical component within trailer air brake systems, specifically designed for trailer brake controls. It's used to enhance the protection and functionality of air brake components on trailers. This Wabco part, with MPN 1811100321, features a cut design at the bottom for increased axle clearance exceeding 50mm, and has a primed base layer. The total length of the midskirt is 2.1 meters. This design promotes optimal brake system performance and durability by providing increased clearance and reliable protection for critical air brake components.

Key Features & Benefits

This part is essentially a valve assembly. It controls the air flow to the trailer brakes – specifically, it regulates how much air gets to them when you’re applying the service brake (your regular foot pedal) and during emergency applications. It manages air pressure, kind of like a traffic controller directing air where it needs to go. It also has a “cut – out” feature – that’s the “Cut” in the name – meaning it can isolate the trailer brake system in certain situations, preventing issues from one part of the system affecting the others. The “Prim” part just designates a specific configuration or size for compatibility. This sits within your trailer’s air brake system, connecting to the air lines that run to the brake chambers. It’s a critical link between your truck’s braking system and actually stopping the trailer. It receives signals from your tractor protection valve and then sends appropriately controlled air to activate the trailer brakes. Think of it as a relay station – it takes the signal and amplifies it into braking power.

Symptoms, Risks & Replacements

If this part fails, your trailer brakes might not apply correctly, or at all. That’s a pretty big deal, obviously. You'll notice if it's failing usually through a loss of braking force on the trailer, or maybe the trailer brakes feel weak or inconsistent. It prevents runaway trailers and keeps everything safe on the road. A faulty midskirt can also cause the trailer to pull to one side during braking. We carry a lot of these at Fixparts Online, and getting a good one installed is always cheaper than dealing with the consequences of a brake failure. It's a key part of maintaining reliable trailer control.
