The guide pins are one of the main components of the caliper. The caliper slides on these pins to maintain a straight line pressure on your disc. If these arent sliding freely then this will create a resistance when you apply or release the brake pedal, hence the slight squeal you can hear when you arent on the pedal. They havent released fully and are basically still touching the disc surface.
Get these greased or as said before sanded down and they should be as good as new.
Are you sure the cut in the brake pads wasnt there already??..These are usually standard with most pads for ventalation.
Nothing beats the sound of a V8
