Rebuild brake calipers?

Mine are the basic 11 inch set up bought from a guy in a newspaper classified many years ago. I think they were off a later model Chevelle or other GM.
I remember trying to rebuild a caliper many years ago and could never drive the seal in. You get one part in the another squirts out. Maybe I just didn’t know the secret (put the seal in a freezer?).
Is it worth doing? Used to be that a reman caliper wasn’t too expensive but I suspect that’s changed.

Anyone got the secret technique for driving the seal in that they are willing to share?

Also what color would a caliper have been from the factory ?

Thanks
 
On Chevelle calipers there is no seal to drive in. There is a square shaped o-ring that fits in a square machined groove and the outer dust seal. They are quite easy to do. If the bore is cleaned up and the piston doesn't have any scoring or pitting on the surface then you should be good to go.The original color is bare cast.
 
These were done by Mike at brake booster.

Thanks. Calipers weren’t actually as expensive as I thought but the rebuilt kits are only a couple of dollars on Rockauto so I’ll probably give it a go.
I watched a couple of YouTube videos and consistent with my memory of trying to do this in the past the guys on YouTube struggles a bit getting the dust seal in.

Does regular paint hold up on these or does brake fluid affect the paint? My thought is that I’d blast them and use rattle can clear coat. Would that hold up?

Thanks
 
Cardone brand @ rockauto is only $29 + shipping. You have to mail in your old calipers.
But they come with a protective coating which is included.
 
For the price of rebuilt ones now I stopped rebuilding them. The new ones are clean and ready to go, all I have to do is bolt and go after bleeding.
