• same for me as user91170, the piston was sticking in the bore such that it would not return to its rest position when the lever was release.

    I have a similar issue with the SRAM Guide brakes on an MTB. Until things warm up, the front leaver just flaps around the dead travel. Still works fine though.

  • Yup, I am now in this boat (with Rival levers). Any advice on what to do if the piston doesn't want to pop back out of the cylinder? Force fluid in via the bleed port?

  • Need more pressure than that. Block all other pistons and force the stuck one out by pressing lever.
    SRAM stuff seems to have a lot of stiction.
