the squealing you hear could be from the metallic in the new pads. a bigger
chunk than should be there causing the squeal, that happens with less cost
pads
did you clean off the rust and lube the caliper slides??? was there dents
were the pads contact the slides? with out lube the pads can get stuck in
those grooves and the caliper piston boot does not have enough strength to
pull the pad off the rotor and a squeal will result
hence the goop theory to silence the pads what it does is glue the pads to
the piston so it can be pulled away from the rotor when the piston retracts
bac into the caliper( but others will tell you different) what about the
rear brakes could they be do for replacement ?
