    I have searched the archives and haven't been able to find any information on the problem I am
    having. My apologies if this has been asked previously. I have the D/A STI shifters double. My
    issue is that that brake levers occasionally will engage the front brake slightly when I go over a
    bump on a trail or the road. I can eliminate the noise by opening the calipers wider. I would like
    to know if there is any adjustment for the spring mechanism that would allow for the pull back of
    the brake function on the levers to be stiffer, and less likely to engage when riding over bumps.
    Thanks David James

    Not really. There is a lot of mass out there on the end of the shifter and it can move when ya go
    over a bump. Ya may try to increase spring tension of the caliper, by pulling the spring loose and
    bending it up, then reinserting it in the caliper. Too bad these very expensive brakes do not have
    spring adjust as they once did.
