on this mod i bought , it has the brake calipers in front of the axle . Is that really the right location for them? I would think behind the rear axle would be better to keep the dirt out or is that so the brakes would cool better or what?

" yes the brakes should be behind the axle tube. "
why is that Robby?

It only matter's if ur brakes r floated. In your case their not cause their mounted in front. If u want to float your brakes then yea u gotta move them. But if u don't want to just leave them its less work to do before the season starts. (It doesn't matter where their located if their not floated)
