    Piston replacement?

    I am rebuilding a set of dual pot Tokico fronts. The pistons were locked in with a slurry if Dot 4, rubber and road grit. The pistons cleaned up shockingly well, but are these scored enough to require replacement?

    Might be retrievable with a bit of buffing down with 1000grit. Anything deeper will wreck the lip of the seal.

      Thanks- I don't mind buffing them out, but I don't want to either cut the seals or just jack brake fluid out. Will probably order new ones and not worry about it. Thank you.
