Best Trailer Brakes for a 3,500 Lb Axle

Question

Question:

I have 4 wheel 26 ft KZ travel trailer. 3500 lb axle, 10 inch brakes, 15 in wheels. The front brakes were just replaced with manual adjust by a rv shop. I plan on replacing the rear myself. I was looking at your site and was favoring Dexter brakes. I wanted to get the best product I can. Can I put self adjusting brakes on the other axle. What is the best brakes you have and do they have any warranty.

The Dexter Nev-R-Adjust Electric Trailer Brake Kit part # 23-468-469 is our best option for a 3,500 lb trailer axle. They are self-adjusting, made in the USA, and come with a five year warranty. You can mix self-adjusting and manual adjusting braking assemblies on different axles without issue.
