The wheel cylinder was leaking where i couldnt see it untill I pulled the shoes off. The shoes look darker than the other side. I feel this would caise an issue once it was heated up. Drum measures round still. The bearings were torqued the way I was always taught tighten untill snug but not over tight. Then back out jist a bit so it still spins with slight drag. There is definatly contamination. Getting another wheel cylinder in and getting it swapped out. Ill be putting new shoes on too. The booster needs to go anyways it has had its own seperate issue. I just feel if im taking all this apart i might as well do that too. Its a 4 bolt master. Do i need some sort of adapter plate all i can find is that they should be the same part. My thinking Is i do not need an adapter.
