79 K10 brake question

[cyneajade]

Hi everyone. My husband is currently trying to replace the front rotors on our 79 K10 Bonanza. We can't seem to get the hub and rotor apart and off the truck. He apparently also broke one of the lugs, so now we really need to get it apart to fix that too. We can get the lock out off and get down to getting the snap ring off, and I don't know if he's gotten down to the spring or not. Can anybody give us an idea of what we're doing wrong or not doing at all that would help us get the thing apart? Thanks!
