Smooth and Powerful Braking

Upgraded the brakes on my old dump trailer. These were a great choice. They are strong and reliable, even with a heavy load. The pre-assembled unit was a major selling point for me.

Great for a 12K Trailer

Installed this on the driver's side of my new trailer axle. It provides very strong stopping power for my 12,000 lb trailer. The 7-bolt flange lined up perfectly. Definitely recommend.

Looks Good and Works Well

I was a bit skeptical at first but this brake is a high-quality component. It fits perfectly and provides excellent braking power. The pre-assembly really cuts down on installation time.

Solid Performance and Durability

I haul heavy equipment regularly and these brakes have held up well. No issues with overheating or fade. The build quality is impressive, and they were easy to install.

Minor Issue with One Magnet Wire

One of the units I ordered had a slightly frayed wire near the magnet, but it was an easy fix with a bit of electrical tape. Otherwise, the performance is excellent and the self-adjusting feature is a great time-saver.
