gee... i'm blushing now... a hug would be thanks enough...

enjoy riding your now much quieter bike, Rachel.

and do recenter those brakes, ok? it might take a bit of trial and error... and don't screw the screws all the way in if possible, it puts things in a bad position at the spring/screw interface.... setr both to about a 1/4" from all the way in, then back out the side that is farthest from the rim until both pads are equa-distant from the rim after you squeeze/release the brake lever....

explanation of the "brake noise"... as the pad first contacts the rim, it will kinda grab and release over and over... if the leading edge(BACK, in relation to the bike) contacts first, the rest of the pad is drawn towards the rim by the grabbing... if the FRONT(trailing edge) of the pad contacts first, the pad begins grabbing and releasing in a rhythm we humans hear as a SQUEAL... an annoying as heck sound. The thing that confuses most folk is that at the brake's location, at least on your bike, and MOST other bikes, the wheel/rim is going FORWARD... this is why i always use the terms "trailing" and "leading" edges of the pad.
