Been a while since I posted here. I took my 2012 Evora S out of storage today and drove it home about 10 minutes. All fine. I pulled into my driveway, which is downhill, and engaged the parking brake after I stopped. Now, all four brakes are engaged and I can't move the car. Is this a master cylinder problem? If the parking brake cable broke I would presume the brakes would be disengaged.
