    brake caliper holding pin substitute

    Lost the little silver brake caliper pin that goes through the brake pads and spring to keep it all together. Needless to say, I was dropping down a run and suddenly had no rear brakes as one of the brake pads fell out (never to be found again). I want to get an early morning ride it but none of my LBSs are open early. What can I use to improvise? Need something metal and bendable that will stay put.

    Any auto parts store has it. Take the one you have and match it up. Then, be sure to have a good bend in the end when installed.
    I guess if you want to be ghetto, maybe some coat hanger wire, bent up on both ends?

    ^^ Call it ghetto, but whatever gets you back on your ride. But yep, it's ghetto.

    Coat hanger wire, paper clips, finishing nails, anything that can be threaded through the hole, then bent & secured in some way. As long as it's heat resistant it'll work.

    A paper clip might be a little marginal. I don't think I would place a lot of faith in that.

    I used a bobby pin just for today and it held up just fine.

    I could've sworn my previous bike which had XT brakes had a threaded pin so I checked today and noticed the caliper hole was threaded. Ordered myself a pair of Shimano brake pins on ebay for a few bucks. I guess this is one of the ways Shimano cuts costs from XTR down to Deore: XTR/XT get the threaded pin, whereas SLX/Deore get the cotter pin. Sheesh...

    On the bright side you will get a new cotter pin each time you buy new pads

    The threaded brake pad retainer bolt also has a 'hitch pin' style retainer clip that attaches to the threaded brake pad retainer bolt to prevent loss.

    That's the first thing I lost.

    It's funny that you mentioned that Travis. When I first saw that little retainer clip on my brakes, my first thought was "that little clip will be the first thing to get lost". But strangely enough two bikes and more than 10,000 miles, those clips are still there. I'm amazed that I've never lost even one of them!

    Yeah, but come on...a bobbie pin? Is that really what that is?

    There's a difference between ghetto and foolish. At least use a wire coat hanger.

    Think about the shear forces on a piece of thin metal (bobbie pin) being exerted on braking. I mean really...

    There no forces exerted on the pin. The pads are held by the slot of the caliper. You can use a twig to hold the pads in place. The pin is only so the pads don't fall out.

    If anyone cares, you can put the M785 bolt in the SLX brakes and ditch the cotter pin for threads.

    Yup, what he said. The pin is strictly used to prevent the pad from popping out, which did exactly that somewhere on the trail...
