The screeching can be caused by metal on metal. That means the metal backing of the pads is against the disc. A common occurance to those that cant be bothered to do regular checks ... It is usually easy to see if you look.

When the pads are at minimum thickness (or less) .... the piston can be past the point where it retracts when brakes are released. Often on an angle as well .... and distorts the seal. Then the problems really begin.
