Getting rust off my disc brakes?

They are Hayes MX4 Mechanical Discs if that even matters, but my front disc has a wonderful splotching of rust, whereas the rest of my bike has none. The rust always rubs very lightly on the left pad, but the non-stop "shhhhhhhhhhhh" of it moving is driving me insane. Is there a quick remedy to this, or do I have to take it off and soak it?

Emerycloth? Scotchbrite?

Brakeclean afterwards, of course, but I don't feel like disassembling them. :cry:
 
its more than just surface rust which would rub off when you hit the brakes i take it? it might be best to just put a new rotor on there not knowing how bad the rust acutally is.

if you are really cheap (or ambitious) you could try sandpaper on it, however i would expect that to leave an uneven spot in the rotor after you were done
 
Fold a small sheet of aluminum foil over the rotor, lightly pinch it on either side and spin the wheel. It will take off light corrosion without damaging.
 
Ah shrp, I should've said it was surface rust. Riding today got rid of it everywhere but the rotors spokes, which aren't rubbed by the brakes anyway. I guess letting it sit a week it got mad at me.😱
 
ha, yea surface rust is not an issue, it will wipe right off once you hit the brakes good for the first time (same as with your car rotors)
 
I have ridden in snow and rain with both my bikes (both have Avid rotors) and nothing ever got a spec of rust on them.

The brakes are meant to heat up on as speed increases and the time it takes you to slow down, esp during down hill runs, they get pretty hot............ the by-product of friction.
 
yup, they are meant to get hot, that is how they stop you, by converting the kinetic energy of you going along the trail into heat energy (remember energy cannot be created or destroyed, only changed between different forms (types, w/e)
