Potential issue with the rear brakes

Feel the rotor cold and see how much difference is there between the outer edge of the flat surface of the rotor (the area not contacted by the pads) and the middle of the flat area where the pads contact? That should tell you how old the rotors are. A dealer would measure both with a caliper and compare to the Porsche supplied tolerances .

It would be unusual for the rotors not to have been changed at least once in 88k miles. Mine were changed at 42k.

Any record of half-shaft rubber boots being replaced? Wheel bearings?

Manual? TIP?

Is this resistance with the clutch engaged?

How sure are you you have released the parking brake?

No record of the wheel bearings or half shaft rubber boots being replaced. Its a tiptronic transmission and the parking brake level is completely released. I have the records from 61k to 88k.

Just went thru the records again and there has been no brake work in the last 28k miles other than a system flush. The previous owner drove it daily from santa monica to downtown LA. Im thinking I may just change the pads and roters to be safe
