Its total length is 2.7 m, contributing to enhanced durability and a secure fit.

Key Features & Benefits

This part is basically a rotary primer – think of it like a starter for the air brakes on your trailer. It takes the initial air pressure from your towing vehicle and boosts it, then sends that higher pressure out to activate the trailer’s spring brakes. It handles the air flow and controls how quickly those brakes engage when you hit the pedal. It's got a rotating valve inside that regulates everything, hence the ‘Rot’ in the name. It also has a release function, letting the air out when you ease off the brake pedal. It sits right where the air lines connect between your truck or tractor and the trailer. It’s one of the first things in line when the brake signal travels, acting as a kind of control center for the trailer's braking force. Without it, or if it's malfunctioning, the trailer brakes won't work reliably, or at all. It’s a key piece in making sure the trailer stops when you want it to.

Symptoms, Risks & Replacements

This is a safety component, plain and simple. If this part fails, you’re really in trouble. You’ll notice if it's going bad because the trailer brakes might drag, or they might not engage strongly enough. A dragging brake will heat up, wear out pads quickly, and even create a fire hazard. Weak brakes, well that’s just obvious, it's a serious risk of runaway trailer or delayed stopping. You’ll feel it in the pedal too – might be spongy or require more effort. We carry these at Fixparts Online, and it’s something you don’t want to put off replacing if you suspect an issue. It’s a relatively small part, but a big deal when it comes to keeping you and everyone else on the road safe.
