Re: rear calipers (s79vette)
No it is not normal to use a sledge hammer , heat and large breaker bar to remove the caliper bolts. They are 7/16 bolts and torqued to about 75 foot pounds. That is a rough guess. I always use a torque wrench when installing them along with a generous amount of anti seize. If you are replacing them with new calipers you could heat the mounting tabs. Actually a large breaker bar is a good idea. It gives you leverage. Try the bar first and if that doesn't work go with heat. If you get them out and want to reuse them run a 7/16 coarse tap throgh all holes first, then anti seize and torque to specs. If you can't find specs I believe 75 foot pounds is close.

Re: rear calipers (s79vette)
Changed mine today on the 67 and they were tight. I used an 18'' piece of water pipe to extend the 1/2 ratchet handle. When they let go it made a snapping sound. Both sides on now and have good pedal. I'm inside now, cleaned up and warm. I love it when things go right, doesn't happen that often.

Re: rear calipers (s79vette)
I think it is a 5/8 socket. If you have a 6 point and a good bar they should break loose. You can get a socket on the two bolts. Make sure you have the right bolts and not he ones that hold the caliper together. Those are larger then the 5/8 socket.
For christmas I got a 3 foot long bar that can break nearly anythiing loose.
Good luck and keep us posted on progress.
