    Got new pads for my disc brakes today.

    Old pads were J04C metal. Was given L03A as replacements.

    Installed them but cant get rotor to fit in. Pistons have been push back (havent pushed to hard) but when I check compatibility of the L03a the BR-RS785 arent listed.

    Any ideas?

    If you take the pads out and look at the pistons are they out or well in?

    I not sure as I've never done it before but having tried something flat and solid it seemed to work. New pads are installed and wheel is spinning freely (and stopping!)

    sticky pistons - 2 mins 40 seconds in.

    2nd may be worth a review

    the 'fan' at the top seems slightly different between these two?

    Ya I've ways had to give the pistons a push in, park tools do a nice little tool for doing it. Any disc rub when the wheel is spinning?

    At the start yes but took the while off and gave the pistons another push. Seemed to take a few goes at pushing them in.

    Did 40km on them there and seemed fine.
