I?ve seen ads for dial indicator setups for truing disk brake rotors, so I assume it can be done. However I?ve never seen any mention of the tools and techniques used to bend/warp/mangle the rotors back into shape.
Anybody know anything about how this is done? What tools? Does the rotor stay on the hub? Do you loosen the 6 bolts, slightly? Remove the caliper? The rotor is a Magura Julie, on a Hase Lepus trike.
