what???i said i had no intention of it!the brake on a monster truck is not fitted to the input shaft anyway!its on the front of the diff,and have seen that bigfoot runs an internal disc brake on its differentials! i was just looking at it from a technical point of view that it would be easier to put a smaller disc on the diff than get ever increasing sizes of wheels and tyres on your car to cater for heavier and heavier brake setups!
