not my car but someone I know.
need to remove rear disc from the hub of a VW Passat - any idea how?
Probably seized/rusted onto the hub.
If there was some way of rolling the car so the hub turns then slamming on the brakes so the disc moves in relation to the hub that would probably
shift it but I cannot see how that could be done.
Hammner? Big puller? Other? Help!!!
Not the same car but I've just changed a rear bearing on a Mondeo. Had to knock seven bells out of the disc to shift it. In the end I put 2 wheel nuts back on loosely so the disc wouldn't go flying, then used a 4 pound hammer and a block of oak
Put some lines in it with a cutting disc on the angle grinder then smash the thing to pieces.
Have you removed the retaining bolt?
Is it internal brake shoes, is the hand brake off, are the internal adjusters de-adjusted?
Give it a big THWACK with a heavy object from in-board.
When I first dismantled my *drum* braked Sierra I spent hours trying to get the drums off. Had never done it before and they'd rusted onto the
hub.
My mistake was trying to 'knock' them off.
In the end my mechanic mate came round to help. 4 good whacks with the copper mallet inbetween the wheel nut threads and the damn drums fell off! Took
him about 2 seconds and I'd spent 4 hours! 
In summary, try hitting the discs between the threads- hard!
Cheers,
James
What year is the car ? 2005 on models with active abs wheel bearings just undo the the big single nut that holds the wheel bearing and take the lot off and seperate the disc from thre hub on the bench be aware it is very easy to damage the ferromagnetic seal on the wheel bearing resulting in an ABS fault.
Best to work out how the thing is put together in the first place.
My 2000 Golf, the rear disc WAS the hub.
Undo the central nut, take the disc off, complete with bearings, leaves the stub axle behind.
No Seperate Hub...
Who's to say that the passat of whatever age this car is, is any different ?
