Changing the rear rusty stuck pin brakes today and asked the wife to put it in neutral to adjust parking brake. So she started it and pressed brake pedal before the caliper was bolted back on. The piston came out to where it was leaking fluid. Cleaned it up and got it back in. The rubber doesn’t look torn. Bled the brakes and it doesn’t look like it’s leaking. Sound ok? Or should I just get a new caliper? Thanks!
