This Wabco Set Screw, MPN 9730023004, is a critical component used within trailer brake controls in air brake systems. It functions as a fastening device to secure components and maintain proper brake function. Measuring 10 x 11 x 24 mm, this set screw is manufactured to OE specification ensuring reliable performance and durability within the braking system. Its precise design and build quality contribute to overall system stability and efficient operation. This little guy essentially locks things in place. Specifically, it secures a lever or arm to a shaft. It's a really simple design – a threaded screw you tighten down to create friction and hold something firm. Think of it like a really secure clamp. It doesn’t do the braking, it just makes sure the parts that do the braking are connected properly and don't move when they shouldn't. On your trailer brakes, these set screws are often used to attach the brake control lever to the shaft that actually activates the brakes. When you move the control inside your truck, that shaft turns, and it’s the set screw that keeps everything connected so that motion translates to stopping power. It's part of the mechanical linkage, so to speak. You'll usually find a few in the brake control head itself. If a set screw comes loose or breaks, that connection is compromised. You’ll notice if it’s really bad, because your brake controller might feel sloppy, or might not even control the brakes at all. It can cause delayed braking, or even complete loss of control. It’s a small part, but a critical one. They can work loose over time with vibration, so it’s good preventative maintenance to check them periodically. We carry a good selection of these at Fixparts Online, if you’re looking to replace yours. It's something you really want to keep in good shape for safety’s sake. Backed by trust: Set Screw (MPN 9730023004) comes with a 12-month warranty!
