Dependable and Easy to Install

Everything included—bolts, washers, the works. Mounted in under 20 minutes. Braking is even and responsive. Great for DIYers who want reliability without hassle.

Reliable Braking for Light Haulers

I use my trailer weekly for landscaping gear. This brake stops true and doesn’t fade. The weather-resistant coating has held up well through rain and road spray.

Self-Adjust Works, But Monitor Early

Use it for two weeks and check for drag. Mine needed a short break-in, but now it adjusts on its own. No more annual manual tuning—worth the upgrade.

Slight Drag Out of the Box

Took a few miles to settle in—typical for new shoes. After break-in, it spins freely and engages smoothly. The self-adjust system kicked in automatically. No manual tuning needed.

Worth Upgrading All Brakes

Began with one, liked it so much I bought eight. The 30% deal made it affordable. Now my trailer stops straight and smooth. Highly recommend for any 3.5K setup.
