Caliper Piston Stuck

[Ct54531@aol.com]

List:

I am now working at freeing the caliper pistons for my 65 4A and have had some
success. One of the four won't budge, however. Given that I am going to
replace the pistons and seal, is it okay to hit it with Blaster. Once again, I
seem to remember a caution against that. (Someday I may actually remember
something instead of just seeming to.)
