What we've learned on the track

[Overdrive]

ProjectM96,

Unlike most other cars out there, Porsche did not design our e-brake to work with the main rear rotors and pads. There's actually a separate set of small shoes that use the inside of the rotor as a drum, so it really is more of a parking brake than anything, and it's not really up to the duty of swinging this car around like other cars, as BYprovider pointed out.

I wouldn't recommend making a habit of doing that, and DON'T use it on track days or after you've been beating on your brakes, street or track. The shoes can lock up against the hot metal, and the same goes for your pads on the rotors. If you come to a complete stop and leave the pads in contact with hot rotors, they can leave a little deposit of pad material on the rotors that will rub each time they revolve until it wears back down.
