• I'm normally setting fire to things with my eyes when working on bikes and I've been known to use a screwdriver to do it. Sounds unlucky. Or maybe I'm just fucking magic. Who knows.

  • :D
    I too have used a big blunt screwdriver, but was gentle and slowly wiggled them back, they just hulled it in there and pulled it back and forth in way under a second. They said it never happened before and that’s how they always did it.
    Oh and ref using the same rotors and cassette on my different wheelsets. One of the reasons is because I’m cheap…

  • flat headed screwdriver + ceramic piston is a big no-no.

    And yes I know Shimano website said it’s ok.
