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.
