I was replacing my slave cylinder the other day when a bolt stripped. I bought a larger size bold and tap and retapped that bolt. I was torquing another bolt that holds the slave cylinder to the tranny - I was torquing it to 12, I think that's what the chilton manuel said. Anyway I stripped that one too. So I started to retap that to a larger size also but then the tap broke off inside the hole. First I tried grabbing the small peice that was still sticking out of the hole with pliers, but that didn't work. So then I tried grinding a flat head screw driver line in it with my dremel. That didn't work either. Then I tried drilling with a regular bit and almost every piece out of the dremel kit. Nothing would drill into the tap. Today I went back to the store and bought a "zirconium nitride coated bit" and a "drill-out micro power extractors" set; the drill-out is supposed to drill a hole into a broken bolt, then you flip the thing around and it has reverse threads so you can unscrew the broken bolt. That drill-out didn't drill into the tap so I tried the zirconium bit. That didn't work either. The tap is made of carbon steel. Anyone have any ideas? I'm stuck here. Sears said that zirconium bit is the best bit they carry. The only other thing I can think to do is heat up the tap with my torch and then try to drill it again when it's hot. What if I just leave that bold out? Will the pressure plate hold the slave cylinder in there without leaking? The slave cylinder has two bolts that hold one side on and one bolt on the other -- I stripped the worst one, the side that only has one bolt.
