VCCA Home Forums TECHNICAL - 1945 AND NEWER 1955-1957 My next front brake problem

I'm replacing the front drums (trying anyway) on a 56 1/2 ton P/U. I've drilled and punched out the 3 rivets, but the hub won't budge from the drum. I've soaked it with penetrating oil and coaxed it with a 2# sledge and a thick aluminum block. Nothing! Were the hubs any of the 56 Chevy 1/2 ton P/U's pressed into the hub (or any other process) that would make it this hard to remove?

Update: The second drum/hub disassemby went just like it should. While driving out the drilled out rivets-the hub fell out of the drum. For what it's worth, one hub had ball brgs while the other had rollers (the difficult one). Both had the nitrile lip seal.

Well, now I realize my problem with the dissassembly. I forgot the old adage-If you have a problem, get a bigger hammer. I put the aluminum block on the end of the hub and blocked up the drum. Then I changed to my full handled 5# sledge, took a 3/4 swing and on the third swing, the hub dropped out. Nothing unusual when I looked it over. No heavy rust, etc. Don't have a clue whether the outboard bearings will ever fit, but I WON!
