I have a Pace Workhorse open 6.5X10 foot trailer. I need some trailer brakes to help me stop and to reduce wear on my brakes when I have all of my stuff on my trailer. I noticed on Dexter's site that they sell complete brake kits with the hub and drum included. Is this what I would need to convert my non-braking axle to a braking axle? Or will I need to buy a whole new axle?
