Minor Scratches, But Works Well

The caliper arrived with a few minor cosmetic scratches on the finish, likely from shipping. Functionally, it's perfect. The pads were seated correctly, and it bolted right up.

Solid Upgrade for My Trailer

Replaced my old drum brakes with these disc calipers and the difference is night and day. Installation was straightforward with the etched instructions. Stopping power is excellent, even with a heavy load.

Fits Like a Glove

Couldn't be happier with this caliper. It fit my 7K axle setup perfectly with the MAT bracket. No adjustments were needed. Just bleed the system and you're good to go.

Seems Very Well Made

Installed this on my dump trailer. The cast iron construction feels very robust. I like the pre-installed pads—it saved me time. Good stuff.
