Did you put the 'anti-squeal' goop on the backside and the ends of the brake pads before you installed them? Those early disc brakes were notorious for squealing when you apply the brakes (especially at low speeds). The metal surfaces on the pads that mate with other metal parts (calipers and pistons) tend to resonate when they are under load. Most times, a little of that silicone stuff placed between those rubbing surfaces quiets the noise.

I know when I detail the tires, if I am not careful and some of the spray gets on the rotors, my breaks have that same hi pitched squeal, not sure if this is your issue or not, but just wanted to throw it out there...

Just this week, had to pull the left rear pads and re-apply. Completely eliminated the annoying slow speed squeak. Another sign that that is the problem is that the squeak goes away when you touch the brakes.

initially i did the put the "goop" on, however it felt odd applying something to a pad that is supposed to stop the car, so i was very sparing at best. i guess now i need to go back and reapply. Thanks for the advice everyone...

Just to clarify, the "goop" does not go on the rotor or any surface that contacts it.

Another way to avoid or eliminate brake squeal - chamfer the leading and trailing edges of the pads at a 45° angle. Then you don't need any goop.

Forget the "goop" get the shim (Plastic) They Go on the" BACK" of the pad. your noise troubles will all but dissapear . the rotor is resonating,lots of corvetts squeal High pitch in breaking . The answer normaly is the shim ,most places sell them.
The goop gets hot and just does not work(on all pads)they do sell pads with angles on them. not sure if that will eliminate this or not.
