Loosening of this stupid bolt required the two of us, one on the ratchet and one with a pair of vice grips pushing or pulling on this stupid fastener. The end result was that we were able to loosen this fastener. The rest of the job went well, just one heads up, the rear callipers require a special tool to turn in the rear calliper piston. This is because the emergency brake mechanize is built into the calliper are instead of being a simple push out action it actually ratchets as a part of the emergency brake automatic adjustment action. With the proper tool (which my buddy had) it is a piece of cake. In addition I took the time to change out the original brake fluid. Mine was very discoloured and brown looking. My plan was to open the furthest bleed screw and let the fluid drain, one wheel at a time. Once again my buddy to the rescue, he had an air operated vacuum pump, 10 minutes job done, nice clean brake fluid.
Man it sure makes a working on your car a lot easier when you have the tools, the job took about 2 hours with my friends tools and help and will end up costing me a bottle of Scotch.
My total parts investment was about $300, the brakes feel a lot better after they were seated in. I should be all set for the next number of years!
