Bent rotor?

I have a problem with my rear rotor. As my wheels spin/roll, they made contact with one of the pads on a certain part of the rotor. While as far as efficiency goes, only a die-hard cross-country racer would care, however, at lower speeds (such as pushing your bike up a long slope thats too steep to negotiate) it can make an annoying squealing sound, especially when wet. I have hydraulic brakes, and while they should self-adjust (i am told), they are most definitely not doing so. My rim is not bent, which leads me to believe there is a problem with my rotor. Is there anything I can do to fix this, or will I have to spring for a new rotor?

a small cresent wrench works well as a rotor straightening tool. Hydralic braked do self adjust but te only self adj for brake pad wear not for rotors getting knocked out of whack

The times I've done mine I just used my fingers. I'd rather use my hands since I'm not worried about a sharp edge digging into the metal.

We ARE just talking about a small tweak after all.

Sneak up on it. The rotor is springy so you'll need to get a feel for how much to flex it to get just the right amount of bend. It's not hard to do at all. If you go too far just push it back a little the other way.
