<VV> Help needed - Brake rotor removal on 4wd- Non- Corvair

[Russ Moorhouse]

Has anyone ever replaced the rotors on a '98 4 wheel drive Suburban

I have a friend who was supposed to be going on vacation tomorrow, but his 
front brake rotor on his Suburban cracked on him today.  He just had them 
turned last week at the local Chevy dealer.

He called me asking if I knew how to get them off.  He was mentioning a big 
bolt that looked like it needed to come off.  Not having ever changed a 
rotor on a 4wd, I didn't know if they were held on any different than most 
cars, where you just pull them off from the plate and studs.  I didn't have 
a clue as to what big nut he was talking about.

I would appreciate any help you can give, so I can press this on to them.
