    Hope you can help...

    Still having trouble with my rear Hope Mono Mini's and front M4's clearing my rotors.
    I have zip tied the brake levers and put a piece of plastic the width of the rotors in overnight to get rid of any air in the brake line, but I am still having problems with the pads rubbing against the rotors.
    Anyone have any experience with this little problem?

    I think I'm gonna try to give either Dirt Dart a call or try to call Brian to see if they can help me through this problem.

    If anyone has any other suggestions (other than getting some Hayes ) please let me know....

    no worries, I don't think the little problem is going to be a recurring issue
    From what I can tell and have read about Hopes, they are bomber but....I just need to get it dialed in and working.

    were you able to mill the disc tabs and square them up...not much room for error with this brake, and the milling seems to be a good starting place.

    As for the M4...can you tell if all four of the pistons are engaging at the same rate ?? I've seen small issues with the timing, but i've found that by isolating the slow piston by holding back the other three and then working the brake lever a few cycles seems to make a difference.... i suppose the brake fluid lubricates the piston also ?? Worked for me.


    later, Chad

    I'll second the recommendation about having your disc tabs faced with a Magura 'Gnanomat' or Hope 'Spot' facing tool. This is an absolute must with any brand of discs except for Avids.

    Facing the disc tabs will make your frame's disc tabs perfectly parallel to your disc rotor. Many complaints of rubbing and squealing brakes can be traced back to misaligned calipers. It's impossible (or nearly) to get the caliper aligned perfectly without facing the frame and fork.

    Not sure which shops in town have one of these tools (and know how to use them).

    Good luck.

    Shuffle the shims

    I use the Mono Minis in a 160 mm rear/ 180 mm front combination. I spent some time shuffling the shims around to get the proper alignment and have had no problems. Just in case, I put a variety of extra shims next to the head of the bolt that mounts the caliper body to the frame. Then I can field adjust if necessary.

    The only adjustments I have made to date are to realign the rear for a new wheel set.
