Slight Wiring Interference Issue

The brake works great, but the wire exit point rubs slightly against the spring hanger on my setup. Added a grommet—fixed it. Performance is 5-star otherwise.

Ryan Smith
Powerful Braking with Zero Fade

Installed on my 10K flatbed trailer. The self-adjust feature works flawlessly—braking stays consistent even after weeks of heavy hauling. No drag, no noise.

Carlos Ramirez
Reliable and Consistently Strong

Using with a Redarc brake controller—perfect sync. No false triggers or weak response. The corrosion-resistant finish already survived a wet spring.

Works Perfectly with Aftermarket Hubs

Had no compatibility issues with my aftermarket 16.5" hubs. Clearances are tight but safe. Braking is balanced and responsive. Highly recommend.

Great Upgrade from Manual Adjust

Glad I switched to self-adjust. No more annual teardowns to reset pads. This one maintains clearance automatically. Smart engineering for heavy use.
