The noise was ear piercing, at lights I'd get dirty looks and people would wind up their windows

After two attempts I have fixed it. Removed all the pads front and rear, cleaned the calipers and cleaned the pads (again). Lubed and installed. Then noticed that I had the clip that pushes the pads forward on backwards.
DAMN!!!

The clip held the pads backwards so that when braking they would vibrate back and scream. Amazing such a simple error could make so much noise.

Wasted a whole afternoon. At least my wheels are sparkling clean now.
