Brake Disc Replacement Help

So I finally got around to replacing my shocks and while I was at it decided to replace brakes. Im stuck trying to seperate the disc from the drum (Front, '97 NAS). Retaining bolts are out. Is the hub now supposed to just seperate from the disc (as in man up) or is there another piece of the hub on the inside side of the disc that is supposed to come off first to allow the 2 to seperate. The shop manual doesnt describe it that way.

I'm not really sure where you are at. You first remove the hub along with the disc from the axle. There are then bolts on the back side that bolt the disc to the hub. Stupid design, but such as it is.

Check for a small phillips countersunk screw that is used to line up disc with hub.
Once it's off, wack it off toward the outside with a rubber mallet, or a regular hammer but using a good block of wood to protect disc.

Leave 3 wheel nuts on to prevent disc to fly out and land on your toe.

Sorry, just realized I'm giving you the procedure for a discovery.

Not on a Discovery 1 either. "Traditional" coil sprung Rovers. RRC, Disco 1, Defender have the disc bolted to the back side of the hub. That is one reason the Disco 1 changed to the smaller hub bolt spacing, to allow for a normal style brake disc.

Attempting to attach photo of disc and drum off truck. Bolts out. I dont see the screw but it seems that there is a piece in the center of the inside side of the disc that is part of the drum that needs to come off to allow the 2 to seperate. Hopefully the pic shows this (first time posting a pic)

You need to tap the hub away from the disc on the flange that contains the rubber seal. Use a block of wood or something to prevent damage to the flange which would occur with just a hammer. I just did this a week or so ago. Here's a pic of my work and a screenshot of what the workshop manual says.

You are correct, I was saying for a D2, did it many times lately swapping and testing ABS sensors.

Thanks for the help. Just needed the assurance that I hadnt left something out. Got a little more muscle (i.e. 12 oz's) and seperated the two. Just frozen together.

Again, appreciate the advice.
