Working on the brakes for my 32 project removing the Hubs from the Aluminum Buick Drums and I cracked the drum. Must have been the process I used , tried to remove the rivet from the inside. Second drum removed the rivet from the top, no problem!. Absolutely made me sick to my stomach!!! And to make matter worse I bought a pair of hubs from a fellow hamber for the project and he did not disclose the the rust. refused to take them back!
