calipers
That is very common. If it's a daily driver, then by all means get them replaced. GM makes a rebuild kit tht is very inexpensive.
Or do you mean the inner seal?
You would have fluid puking out most likely and the piston would be jammed in place.
New calipers aren't as expensive as you might think. New C5 calipers can be had for around $100 each, depending on where you shop and/or the relationship you have with the parts guy..
As far as "bolt-on" goes, many will argue that it won't work for various reason.
But C5 calipers are on my race using the F-Car abutment bracket, rotor and pads.
No issues for the last 3 seasons.
But as noted you will melt the dust boots, I also installed a set of Doug Rippie Motorsports stainless steel pistons. They don't transfer the heat to the brake fluid the way the stock aluminum pistons do. But they do toast the dust boots the same way. Since the T1 car is track only I don't even install the boots.

If its a street car, then replacing the boots is a must do.
A track car typically doesn't see the harsh conditions nor the number of miles a street car sees. So, dust boots are optional.
I have Rippie pistons in my C5 calipers and noticed a significant change in fluid discoloration.
