Stripped Brake Bleeder Screw?
#2
I'm guessing that it's most likely rusted shut. use a torch to heat up the area just below the bleeder, tap the area a few times with a hammer to loosen **** up, then use the vice grips to turn it. You have to do it fast so it does'nt cool down before you attemt to turn it. Or just buy a caliper for like $50!!

then you probably just overtightened the bleeder last time you bled them.
they don't need to be very tight to not leak, people tend to overtighten them though... like oil filters.
be careful with the torch too, there are some rubber seals in the area that you don't want to overheat. Just remember it's aluminum, it doesnt take long to heat, a short burst of torch will heat the area around the bleeder pretty well, just work fast. If you keep it on you'll just end up heating the whole caliper, boiling fluid, and maybe damaging seals. i'm assuming it's the 4 piston calipers..

I had this happen to me when I did the brakes on my 88. I ended up drilling the bleeder screw out and retapping the hole. Just be careful not to drill too deep. My caliper was also off at the time so I had it in a vice.
