How to re-terminate frayed brake cables? I've bought and installed new cables for my bicycle, but I didn't have any cable-ends to crimp the ends. I've been riding for a few days now and just noticed that one of my cable ends has unwound itself due to movement or vibrations. Now I have a frayed set of wires sticking out of the end of my brake calipers.

Is there a good or proper way to reset these wires back to their original position so that I can crimp the end of the cable properly? Thanks
Seth's Bike Hacks channel on Youtube has a video that specifically addresses this problem:


                
            

A quote: 


  When I showed the cable fray trick in another video, some of you thought I was playing it in reverse, but it’s true! You can unfray some cables by twisting them from the base and working your way back up. This works particularly well on cables that were recently frayed, and usually by clipping a little off the end and adding a new cap, you’re back up and running without needing to swap the whole thing.
