I bought a used set of CTS-V calipers from a member and have been getting them ready for powdercoating. I've blasted them and partially disassembled them (removed pistons & boots) with nothing left to do but remove the piston seals.

And therein lies my question. How do you remove/replace the piston seals and do I even need to do that? I don't want to attempt to remove them and destroy them in the process leaving me no choice but to replace them. Thanks for any info!
