|   Can you/ how to straighten a warped rotor? | bugeye
Sep 21, 2001 6:06 PM | | I've been riding on Avid mechanical discs for about 2 months. Love the power and modulation, but have just noticed the rear rotor is now slightly warped. It's not enough to be a real drag, but you can visibly hear the scraping against the pads when the warped section rotates through the caliper. I could, of course, just increase the distance of the pads from the calipers, but then my brake lever has too much travel in it for my liking. Has anyone had any luck straightening the Avid rotors, and if so..how?
Thanks. |

Sep 21, 2001 7:12 PM | | ......about Avid rotors but I've straightened lots of other makes with 100% success. I can't see what's different or special about Avids. In fact I haven't owned a rotor that didn't need straightening.
I use a few methods, alone or in combination - whatever it takes - fingers, hands, adjustable wrench clamped onto it both on the friction surface or one of the arms.
Creativity, patience and passion count for lots.

Sep 21, 2001 8:52 PM | | Whichever method you use, though, wrap a clean rag around the part of the rotor you're touching, DON'T touch it with your bare fingers, you'll leave oil on the rotor, which will contaminate your pads if you forget (like I have) to clean it off afterwards.
You can wrap the rag around the warped point, tighten an adjustable wrench over the rag, and gently pry the rotor in the correct direction. 9 times out of 10 this works just fine, but do it slowly, so you don't bend it out of true in the opposite direction. You can also use just your hands, but I've found the wrench to be the most effective.
Overall, though, it's not really something I'd worry about too much. Unless the pads are dragging heavily in one spot, that is. If it's just a mild warp, it can work itself back out after a few hard rides. My Avids will rub one ride, and not the next.
Also, if the warp is minimal, you can try moving the rubbing pad out a click or so, and the non-rubbing pad in a click or so, and see if maybe centering the pads a little better helps. If it does, then move them back to where they were, and realign the caliper itself.
