This may have been done but I'll ask here anyway.
I replaced my front rotors and pad today and was fairly uneventful until I fitted the last left side brake. I test drove the car and noticed a noise coming from the left side (thump, thump, thump) sounded as if something was hitting the rotor everytime the wheel rotates. All looks good after a second inspection. Disk is clear of any suspicious items.
When I opened the caliper again for inspection and jumped on the brake to extend the caliper pistons, only one came out all the way with the second only coming out halfway. Would this indicate that one caliper piston is seized is not retracting back into the cylinder? I'm suspecting that after applying brake pressure, half of the pad has pressure due to the the seized piston which is still meeting the pad causing the noise/vibration.
What does a Caliper rebuild require? Where do we get the 'special' grease to do it ourselves if we can?
