Chosen Solution
I just replaced the idler arm bracket for my Craftsman lawn tractor with 46" deck and forgot to check before removing the old one if the bracket (metal bar that holds pulley, brake pad, clutch spring on 46" deck) is supposed to be bolted back on tight or left slightly loose. It makes sense that it is slightly loose as otherwise the brake stop always pushes on the pulley. Thanks.
Problem seems to be solved with repairclinic.com video again.
