Can you repair a wobbly disk rotor????

During transit from Lagos, Nigeria to South Africa the rear rotor on our MTB tandem got ever so slightly wobbly. It is rubbing on the pads and makes a irritating noise. Any way to fix this. A local messageboard suggested that you place the disk on a heated solid electric stove plate with a large pot filled with water on top of it. Could this work or were they fibbing????????

Park (and probably others) makes a rotor truing tool -- looks like a wrench with a very long narrow slot that you slip over the rotor to bend it back into true. You could probably accomplish the same with an adjustable wrench. This isn't uncommon -- it is hard to keep the rotors running absolutely straight so there isn't some minor contact with the pads.

Just remember when you're bending it back with supposedly an adjustable wrench, that you're not bending the outer circumference of hte rotor, that does nothing. You need to bend the "spiders".

Put a wood block over it(so it covers a large area of the disk) and give it a couple "love taps".Couple of light taps should do it.A dial indicator makes life easier.
