Time: 3:59:06 PMParking brake was engaged while being driven. You will have to take off both sides and do one wheel at a time, inspect and adjust the mechanism, then reassemble, your P brake should work after that without further adjustment of cable or mechanism. You might buy a haynes manual to outline the removal adjustment and installation. I can't remember which piece pops out of sync with the others but that is what I've had happen to the parking brake.
Check for brake fluid at the master cylinder and slave cylinder on the clutch system. To check the master look up under the dash for leaking oil from the cup and shaft that connects to the clutch pedal, on the other side of the firewall is the master, there is a line on the side of the brake master reservoir which feeds fluid to the master clutch, check your fluid level too.
The slave is outside the bell housing on the bottom near the starter (I do 924T so I'm going from memory here) check the slave where it bolts to the housing if it is leaking it should be wet or built up with gunk. If it is the slave replace it. The system gathers water in the lowest spot which is the slave and pits it beyound repair. You will probably be better off pulling the starter when bleeding the clutch. Remember to disconnect the battery if you remove the starter.
If the system was low, then bleed the clutch slave, it is a pain in the but and takes some time and patience to accomplish manually. I prefer to power bleed the system from the resevoir down. If the system was low you should flush and bleed the brakes at the same time.
Porsches need the brake and clutch hydrulics flushed at least every two years just to save on buying expensive replacement parts. If you street race or drive real hard, well you need to check the system on a six month basis and still do a flush when the fluid gets dark.
Good luck
