With Huck brakes, it takes a while for the new shoes to wear down a bit and better match the contour of the drums. Back in the day, when labor was dirt cheap, they ground the new shoes until they matched the drums. You can accomplish the same thing by driving the truck and let the drums do the work for you. Just leave extra space between you the guy in front of you until they get right. After that you should be able to stop on a dime. (Your dimes may vary.)
