    Looking for pics of v brake boosters

    Looking for pics of your brake booster. Having trouble with my install on a set of xt v brakes (m739). Love to see details of the spacer area.

    Thanks

    No pics, but the spacers (if needed) usually go between the caliper and the booster.

    I've used brake boosters on several frames and forks, and they can make a HUGE difference. I am surprised they never caught on more.
    15mm is a second-best solution to a problem that was already solved.

    Nice

    So, to the spacer issue, in the pic above there is just a washer between the booster and calipers. In some cases, the booster might need to be spaced out a little farther, so you might have a spacer in there.

    Wow, that rim looks pretty scary! I'm guessing that brake pads last about a day...

    It is a trials bike with the braking surface ground for texture. no modulation, just full grab.

    To the OP, I have xt v-brakes on one of my frames, no booster on right now, but I do have one. I seem to remember spacers maybe a little less than a half inch between the caliper and the booster. The paralellogram mechinism on the xt brakes sticks out quite a bit so you need to make sure your spacers give enough clearance between the booster and the brake arm so they don't bind.

    edit:

    threw the booster on my bike tonight and snapped a couple pics. Spacer is about 5/16" but could be a bit thinner, but not much.
