Great for DIY Trailer Owners

As a weekend builder, I appreciate how complete and pre-assembled it is. Just bolt on, adjust, and go. No extra parts or guesswork needed.

Excellent for Fleet Repairs

I manage 12 utility trailers—bought 8 of these at 30% off. All installed without issues. Now I’ve got a reliable, cost-effective brake standard across my fleet.

Dependable and Consistently Built

I’ve now bought four of these. Every one has been identical in quality and fit. The bonded pads last longer than the old riveted ones.

Slight Resistance at First

Use required a few cycles to fully seat the pads. After that, it released cleanly. E-coating looks solid—no rust even after wet road use.

Great Value, Strong Performance

Stopped shopping for OEM after trying this MAT unit. The friction material grabs well and doesn’t fade. Excellent for my boat trailer with surge brakes.
