Did rear brakes on my daughters (gasser) MkIV Golf. Used the HF piston tool to try to retract the piston, but it got all messed up (caliper was siezed). Handle all bent, plate bent, roll pin (which I have replaced) sheared. Guess I got ten years out of it, so I'll just replace it with new.
I think she had the original pads and rotors on the car.
One pad had zero friction material on it. Rest were very thin.
Had to get new calipers, and NAPA was the only place close with both rears in stock. Right side swapped without much fanfare, but the top bracket bolt on the left started stripping, so I just left it alone and reused the original with the new caliper.
Found that her left rear wheel bearing was bad (noisy but no movement/looseness). I would've liked to have replaced it as I was doing the brakes, but it was not in the cards. She ordered a new one from idparts that I'll install when it gets here.
