one ton disk brake story Also, I find it interesting that the folks selling the 1/2 ton 6-bolt kits have "Patent Pending" all over thier stuff. Are they going to go after all the guys who built kits almost identical to theirs? What about the home built kits that have been rolling around on trucks for the last 10 years? Between Phat, Buffalo and the 4x4 caliper/disk setup I put together . . . seems like it would be tough to dispute prior art. Piddly patents pi$$ me off.
