Hello,

I have a 1981 300TD turbo 617 952...402000km. I replaced the front rotors and brake pads, and noticed that the new pads are always touching the rotors, even when brakes not applied. I checked the rear brakes and that is the same. Should they always be rubbing slightly or should the piston return to a position that takes the pads off the calipers by a few mm? I'm wondering if my pistons need some brake lube or if they might be shot? A related question is how freely should the wheels spin when car is jacked up?

Thanks for any insight or help!
