Do what i do turn the music up
on a more suitable note make sure that there is no crap on the hub behind the discs and check that the fittin kit on the rear shoes has been fitted propperly and not touchin the inside of the drum or the inner hub

If you have disc's all round remove the pads and give the braking surface a scrub with 80grit sand paper to take the glaze off the pad then apply some copper grease to the backing plate face
For rear drums chanver the two edges of the brake shoe lining with a flat file and blow any excess brake dust out off the drum area..
No more squeal!!!!!!

Anti-squeal shims might be a good idea too.
Once driven, forever smitten.

i had a similar problem b4 on another car, the problem turned out to be badly bent caliper slide pins, it looked like whoever done the brakes used a hamer to put them back together, causing the brakes to be not making the correct contact with the discs, if all them cures dont work, try replacing the caliper slide pins, i believe the parts are actually part of a brake caliper carrier kit and arent available seperatley
