Thanks Robert!
I have succeeded in loosening 1 of the 2 bolts that hold the wheel cylinder to the plate, the other has rounded off. I also got the brake line loosened as well. Gotta love a propane torch!
I think I will leave the brake plate in place, and grind off the "hump" on the wheel cylinder where the stuck bolt resides. A little 3lb maul action should finish the removal.
All {of course!} after a thorough visual inspection and comparison of the new cylinder to the old one! Some nice new hardware and the job is almost done.
