Well gone and done it now. the extractor broke off in the hole. Thought I
was going easy, had soaked the thing in PB blaster and was turning it by hand
so as not to break it or create metal shavings. I guess, as one wag
suggested, I need to pull the thing off and take it to a machine shop. Have
started to pull the caliper off and it does not want to budge.
I am getting pretty close to selling the car, I am not beaten yet, but the
tide of battle is turning against me. This is my third MG and undoubtedly the
hardest one yet to get on the road. I wanted a challenge and boy did I get
one with the MGC.
I think I will go work on my TD for a while and let this beast sit.
