Sort of insipre by another posting about drifting and viewing drift bible. I notice when I apply the e-brake while the car is moving a loud clunking noise occurs
Is this noise normal and what is causing it?
Other than brake&tire&drive train wear will the clunking noise cause damage to other parts of the car (specifically where the noise comes from)?
Thanks
Lawrence - use care when applying the e-brake on rear wheel drive cars. If you yank and brake too hard you will put a lot of strain on the drivetrain. Think about it, if you lock up both rear wheels, the output of the transmission must stop turning, which in turn means the engine needs to stop turning. At higher revs the engine has a lot of angular momentum - the clutch, tranny and driveline are going to experience extreme torque (twisting).

Good point. I guess I will try putting the clutch in then e-brake..
BTW, I was pulling only a very slight amount then heard that awful clunk. Does any one know how the e-brake is activated? Does it work with existing rear calipers or it has another set of brakes?
Clutch all in and the e-brake still make that crazy noise.. Help
I have experienced the same noise. The technician at the dealer said it was due to the shifting of the e-brake pads, which by the way are on the back inside of the rotors. He claimed it was normal and the 997's also made this noise. He also said you weren't supposed to pull the e-brake while moving. I said it was an e-brake. Isn't that used in case of brake failure? He didn't have anything to say, but it was normal. I find that this is normal. I have never had a car make this kind of noise when you pull the e-brake. Anyone else had their car at the dealer for this trouble or know why such a horrible noise?
The parking brake uses cable actuated drum brakes located inside the rear brake disc hats. They're not very robust and are meant to be used as a parking brake. I'd guess that if used to actually stop the car from speed in the event of a total loss of the hydraulic brakes, there may not be much left of them.
That's correct, it's a parking brake, not an emergency brake.
The owner's manual says only use it after you have come to a complete stop. I'm guessing that if you yank on it repeatedly while driving, and something breaks, the dealer will not consider it a warranty repair.....
I know some people are trying to do hand brake turns. Best not.
From K-ManS's girodisc article, the parking brake mechanism (basically a drum brake, using the inside of the rotor as the drum):
The rear rotor has a deeper internal housing to form the parking brake drum:
