I am in the planning stage of building a mini. Since I am 1000 miles from the nearest ocean, I will be doing most of my land sailing in a large parking lot. I do not want to do body damage, to either myself or any parked cars,therefore I will want to put a brake on the mini. I think a disc brake would be the best. Any ideas how to put one of those on the wheels? Would it be best on the front or the back? Thanks.
