Caliper piston removal options

[1970 cuda Joe]

That caliper has the seal in a groove of the housing & the piston moves across it. The nwe seal will need to have a good seat in the housing. The piston will most likely need to be replaced. I'm really surprised the piston hasn't come out yet....Joe

It sounds like you're enjoying the challenge but if you decide to seek professional help I recommend sending it to Brake and Equipment Warehouse in MN.  They do great work and are very in tune with collector car restoration work.  They rebuilt my calipers, master cylinder and proportioning valve.

Thank you @Floyd.  I talked to Brad a few months ago.  I was surprised he was available and was kind enough to walk me through best practices for packaging and shipping parts as well as many other details.  The eventual goal is to have Brake and Equipment Warehouse do everything but for the short term I just need to get the car out of the garage in order to gut and remodel the space.
