I'm not suggesting. You should exhaust every possible avenue of approach before you do something drastic - like getting a better brake-set. But I had a set of the Avid SD 3's that came stock on my Trek 7.5 FX. And they drove me knutz. I tried everything I could think of.
Now I have Avid SD 7's. Not a problem. Silent and stays in alignment. Stops me on a dime. And the SD 7's do get rave reviews.
