well turns out it was ez. i do have a bunch of torx but i guess when i put on the old ones at 50K, i messed something up. a few seconds with a normal drill bit and the head popped off and when i got the rotor off the screw just unscrewed as if it was brand new.
i already had removed the other screw 50 ago so obviously it truly is not needed. so lets hope these OE pads last 100K like the others and the rotors at least 50k
i do have one question. what is the official wrench to hold the inside of the pin while you are tightening the caliper bolt on the slider? my 11/16 seemed to fit on the one but then not the other. it was like the lip was too close and i couldnt put on the wrench. i had to use vice grips as a stopper to tighten the caliper bolt.
is there an officil torque for the slider bolt and the huge bolt that holds on the caliper to the car? i just tighten the heck out of it mostly.
