1. Take the pads out and lightly sand to remove any glaze
2. Lightly sand down rotor/clean with methalyated sprits (dentured alcahol).
3. Replace wheel, re-align caliper.
4. Do a few minutes of really hard braking and heat up the rotor/pads.
5. you should be right!
I had EXACTLY the same problem with my rear Hayes brakes/pads. I bought a set of EBC Green pads (quiter pads) for about $20AUd off eBay, and squeel is no more!
