    Here is the link to my instructions on how to get them out.

    If you stripped your bolt already, use a pilot drill bit, then make the final removal using a 9/64 drill bit. It only takes a few minutes and so long as you're patient, no damage will occur. The bolt head came off on my bit in my case. Just keep hitting the bolt with the drill, looking every few seconds. I removed the cover and unthreaded the shank of the bolt by hand, as the cover is very thick and a lot of it is left above the body of the master cylinder.

    All steel T-handle wrench tap on top while applying turning pressure. If you go the drill bit direction get a reverse bit and run your drill backwards.

    A reverse drill bit will not pull the bolt out. The heads are shallow, especially after being stripped. In addition, they also have significant force on them and that's not relieved until the head pops off. Due to that, the bolt will not back out.

    A tap will not work, either.

    If one needs to drill a bolt or bolt head out a standard bit will snag the bolt to create the pilot causing the bolt to tighten. A reverse bit will also snag the bolt but is going in the unscrew direction working like a impact in a sense. Worst case it does not back out the bolt but you still remove the head which releases the pressure the top cap is applying to the bolt.

    Work with the force not against.

    Doesn't make a difference. The bolt will not tighten, especially since the Hope covers are stiff and offer little give. Mine popped right off.

    An impact doesn't work on the principle of reversing. Impact tools have specs available on how many impacts per minute or second they generate. They work just by doing what their name implies: create impacts and overcome inertia of an object or coupled with high torques behind them, impact a stuck fastener repeatedly with shock torque. Or they can always be used to tighten...

    those screws don't need that much strength to be removed. Have you tried a small (sunglass) flat screwdriver? make a little pressure with the rigth width one and you should be able to uncrew out of there

    Guess all those moto caps I removed with striped or seized screws was an illusion.

    Most of what you say here is most obviously a figment of booze and your imagination.

    since you guys have the same intrest as me, I have also got squeeling back brake but not a squeel more like a braying sounds like a donkey and it vibrates the bike some much so that it vibrates the saddle :O its not a bad thing but its putting me off tried sanding the pads (hope sintered) then tried EBC (red) and after a while they did the same, i have a 180 hope floating rotor on my 575, and it happend when it was very dry on big decents. now it happens on little decents to.

    When you say floating I assume it's the two piece with rivets. Check the rivets that they are making a good sandwich, if the rivets get loose they will vibrate and the rotor can move around. Also check the caliper alignment making sure the rotor is in the center and both pistons are pushing the pads to the rotor at the same time.
