    How do I repair a broken brake pad pin?

    Well, I did it this time I'm still not sure how I managed to do it, but it seems my wife wasn't as surprised as I was. Wonder if she is trying to tell me getting the dumb-ass award.

    While installing new brake pads on my Avid XX's, I managed to cross-thread the pad retaining pin.....and snap it clean off

    I am certain that I can remove the pin, and am certain the threads are screwed up. I am also sure I am not the only person who has done this. So if you could stop shaking your head and mumbling the word "fool", I could use some sound advice.

    If you can't repair the threads-tap etc-a split pin will take care of it.
    Split pins are common for many Shimano brakes-simple/easy/inexpensive fix.

    Many thanks from the dumb-ass award camp! I too thought a spit-pin might be an option, now I know for sure that it is. I was also considering the following....what do you think?

    If the threads don't clean up, but have not elongated the hole to where the pins allen head still rests flush against the brake body:
    1) Get a new Avid pin and clip
    2) Insert it through the hole as I would with a split pin
    3) And use the associated clip on the other in to hold it place.

    Maybe a drop of lock-tite on the remaining threads.

    It must just be the engineer in me However, the existing pin is securely in place (guess I made sure of that when I broke off the head). So I will execute its repair when I need to get the pads out again. With new pads and my wife riding it, that should take YEARS!!!

    Thanks as always for your assistance.

    All the pin does is stops the pads from coming out, not load bearing. So the pin screw plus the end clip will work just fine. Even a twig/toothpick will work.
