    Anybody know what size the front brake bleeder screw size is on the stock calipers? Are they special enough that a standard auto parts store purchase won't work?

    Try Metric........ A lot of times a 12 point wrench works better.

    I can't remember if they are metric or SAE, but I do remember buying one from an Auto parts store. Real easy to match if you carry old one in.

    Yours should be the same as mine 1/4-28 and you need a 5/16 wrench or socket to remove it.

    Uh oh. Guess I'll pull one and take it to the store with me. Hoping to save a trip. Thanks for the responses.

    Interesting... this is where a screw thread gauge comes in handy. :)
