Are there any weird marks or scores in the brake disc? Could be something trapped inbetween the disc and pads.

take the pads of and blow clean them and the discs.
pads are made from all sorts ive quite often found random bits of metal in them, just pick them out f you find anything

probably just high nickel content in the pads, thats what happens when asbestos is banned. bastards

Take the pads off, make sure the anitvibration doo-dahs are still in place and smear a load of copper grease on the backs of the pads.

Rob, remove the pads. Cane them and the discs and calipers with brake cleaner.
Clean the channels the pads sit in with a screwdriver and a wire brush.
Spin the disc (both sides) and knock off any part of any lip that is proud rust with a screwdriver as it spins.
Place the pads on some fine emery cloth on a perfectly flat surface and flat them off, also, if you've got a bench grinder, it can be a good idea to put a little angle on the edges of the friction material at each end to prevent chatter and harmonic vibration during low speed braking.
Then cane the pads again with brake cleaner.
Refit them with anti squeal compound (copper slip or similar) on the edges of the pad back plates where they slide in the caliper channel, and the back of the pads on the areas where the piston/slide portion of the caliper makes contact.
Make sure you've got any shims/anti resonance plates in place on the back of the pads of course.
It can also help to spend a while roughing both sides of the discs with some course emery while spinning them.
Rover used to sell a black fluid that came in a metal pot with a brush in the lid. It was like a very watery satin paint and it was a treatment for the surface of the pads on the Rover 800s.
They used to suffer with bad brake groaning at parking speeds due to the pads resonating/chattering on the face of the disc at very low speeds with the brakes applied lightly in gear.
It was amazing stuff and realy effective at eliminating the problem, and only took about ten minutes to dry completely.
It might be an idea to check your local MGR parts outlet and get yourself a pot if it's still available.
Needless to say, you apply the stuff after facing the pads and removing the sharp edges and washing all the dust off with brake cleaner.
Hope you get it sorted.
