What makes these special is the slotted clevis – the U-shaped metal part at the end of the cylinder rod. The slot in the clevis allows a bit of movement or “play” in the brake lever. This is especially useful when using the trailer’s mechanical handbrake, because it stops the brake lever from jamming or binding when the brakes are applied or released. It gives the lever just enough room to move freely without putting strain on the system.

In short, the slotted clevis helps keep your handbrake working smoothly, even if the trailer or load shifts slightly. It’s a small feature that makes a big difference in everyday use.
