I have a pal who restores old Indians & has greatly increased the power of the front drum brakes but has found that the added heat generated makes the alloy brake shoes grow to much. He wants to drill (6) 5/8" dia holes on the side of the brake drum and (24 to (36) 1/8" dia holes around the outside circumfrence of the drum between the two cooling fins. Has anyone had experiance drilling holes in a drum brake like this or know of bikes that have them & is it good or bad???
