Be sure to replace the flex hoses as well. When they get old,
sometimes they can get plugged and act as one-way valves. I had this
happen to me on a Volvo and, more recently, on my TR8. The Volvo disk
got hot enough to warp when the caliper stuck (a nice cherry red :-).
It was a big surprise to me to pull the caliper off and find it worked
fine, but no fluid leaked out of the flex hose.
The '8 got hot enough to boil the grease out of the bearings (not a
pretty sight, but replacement parts should be in today).
