front brakes question?

[mothertrucker424]

i am going to be doing brakes on my 72 k10 for the first time
i will be replacing the rotors because they look to be original and never cut before
but i do not know how to get them off??

i know i need to remove hub locks
but when i do will they spring apart or will this all be a simple task?
i will also be rattle canning all parts black again and the plastic lock outs blue again

so any help would be great i remember seeing a couple of pics but can't find them now

thanks for any help
