Brake Calipers

["Robert Wiseman" <robman@telocity.com>]

I decided to replace the seals in my brake calipers.
I was able to get both pistons out on one and only one piston on the other.
When I replace the pistons on the one that both came out of I could only get
one in part way and it is stuck.
I have tried several "Tricks" to get them out.
Any suggestions.
Also, are good new or rebuilt calipers available?
Help,
Rob
