The brakes seem to be working good. They worked real good with the 11.00/20's on it, but I knew adding 2,000 pounds of rolling weight was gonna have some affect, but they still work very well. I think if I stood on them hard enough I could get all four tires to slide. They may improve once they break in, I put about 20 miles on it today, but not much stopping. Here are a couple pics for size comparison. Oh, and as far as making brake kits, they will have to be in the future sometime. I'm about to start work with the fire department here in Jax, and the first year I will be busy studying. But, after I get settled in, I'll probably build a kit and see how well it sells, then go from there.
