Reliable and Durable

I haul equipment daily, and this brake has held up perfectly. It's been a few months and the performance is still excellent. A durable, well-made product.

My old brake assembly was shot, and this was the perfect replacement. Fit my Dexter axle without any problems. Braking power is restored.
