I have a pretty new bike with a Record group. After about 400 miles my brake pads have begun to sound like a teapot reaching a good boil going down fast descents (it happens after a couple of seconds of hard braking once the pads are heated). Is this normal or is there something else that I should be looking at? I cleaned the pads and rim really well to make sure there was not any debris...
They're glazed. Pull the pads of and scrub them with a file, emery board or even the sidewalk to knock of the glazing. When they are soft and fresh (think new pencil eraser) reinstall them and they'll be ace.
They may need proper toe-in. When you reinstall them put a business card under the back part of the brake pad to space to slightly of the rim so the front part hits first. This will help stop the noise problem.

It's either a toe in problem or rim and brake pad cleaning problem. Rubbing alcohol, clean the rim. File down the pads a bit and remove debris. Then toe in the brakes a bit.
