How do you remove broken bolts?

Answer

If you can get at them with a drill buy an easyout which is like a drill bit but the threads are backwards. The size of the bolts will determine the size of the easyout and the size of the drill bit to use. Drill a hole down through the middle of the bolt and then insert the easyout and turn counter clockwise. The bolt should come loose. Soak the bolt first with liquid wrench or some other penetrating fluid to loosen up, the longer the better. If you have room to put a pair of vise grips on the bolt then this method would be easier. The secret is to soak with the liquid wrench for as long as possible.

Answer

I have used the PB Penetrating Catalyst to unfasten one of the rusted and broken bolt on my old brake caliper. It took few spray and overnight to break the tought broken bolt but it's better than drilling the threads in my opinion. This product is amazing and I have told my friends to try this as well.
