Slightly Scratched Finish

There was a small scratch on the finish of the caliper, likely from shipping. It doesn't affect the function at all and the caliper is performing great. Still a good product.

Better Than My Old Calipers

Replaced a caliper on my boat trailer. The old one was a different brand and always had issues with sticking. This new one is smooth and the bleeder cap is a great feature to keep out dirt.

Minor Issue with Bleeder Cap Fit

The bleeder cap was a little loose, but a new one from my local parts store fixed it. The caliper itself is fantastic. Installation was easy and the braking performance is excellent.

Perfect Fit for My 6K Axle

The specs were spot on. This caliper bolted right up to the existing bracket without any issues. The laser-etched guides were a nice touch and made the bleeding process simple. Quality product.

Smooth and Powerful Braking

Replaced a seized caliper with this one. The braking is now perfectly balanced and feels very powerful. It's a great part.
