Wabco 4700157304 Connecting Rod

Description

This connecting rod is a critical component within trailer brake control systems, specifically designed for air brake applications. It functions as a mechanical link, transmitting force to actuate the trailer brakes. This rod is manufactured by Wabco with MPN 4700157304 and adheres to OE specifications, ensuring a precise fit and reliable performance. Measuring 11 x 11 x 74 mm, this component offers durability and consistent operation within the air brake system. Its precise engineering contributes to improved braking efficiency and overall trailer safety.

Key Features & Benefits

This little piece basically takes the motion from when you step on your brake pedal in the truck, and transfers that mechanical force back to the trailer's brakes. It’s a simple push – pull action, really. It physically links the brake pedal lever to the actuator that actually applies the trailer brakes. There’s usually a linkage with several of these rods to make sure the signal gets there reliably. Think of it as a vital messenger. Your truck's braking system needs to tell the trailer to brake, and this rod is how it does that. It’s part of the whole air brake system, specifically how the control signal travels. It doesn’t do the braking itself, but without it, the trailer won’t respond when you hit the brakes. It’s found specifically in air brake setups, which are common on heavier trailers.

Symptoms, Risks & Replacements

It's important because it’s a safety thing, plain and simple. If this rod bends, breaks, or comes loose, the trailer might not brake properly, or at all, when you expect it to. That's obviously a serious hazard. You’ll notice if one fails pretty quickly – probably some slack in the pedal, or maybe a clunking sound. It’s a relatively inexpensive part to replace, and it’s far better to address it before it becomes a problem on the road. We carry a good selection of these at Fixparts Online, and it's one of those things where getting the right part is crucial for everything to work correctly.
