remove the wheels
remove the little bolt
remove the calipers
remove the disc
there may be varying degrees of difficulty in these procedures

From what I remember the hub nuts undo in opposite directions. One side
goes clockwise, the other goes anticlockwise, but I can't remember which
side does which. Anyone know?

i think you are referring to the law in physics about direction of
rotation and the tightening of the nut.  the dodge people first started
doing left handed threads on vehicles a long, long time ago.  

that is why the passenger side wheels have right hand threads and driver
side wheels has left hand threads.  

if anyone has ever lost a wheel due to loose lugnuts, it is usually on
the driver's side because if they are not fully tighten - will back off.

hope this helps.

go to www.contour.org and get just about anything you need on a

very informative web site on this ford vehicle

I wouldn't have thought so - just the caliper.

If there's a retaining screw holding the disc in place (doesn't do much
except for aid positioning of the thing), and it's old-ish, make sure you
don't round it off in the middle - something very easy to do if the
screwdriver isn't an absolutely perfect fit.  It might even be neccessary to
buy a screwdriver socket bit that an exact fit, as for a couple of quid
it'll save you hours of swearing!  Then replace the screw with a new one.

Thanks for all the comments.

Tackled the job today. One disc came off with gentle persuasion, the other
needed more invasive surgery with a grinder, lump hammer, chisel and a
healthy amount of anger : )

Job done.
Cheers all!
