I'm posting on this board because truly I need your help.
This past Saturday I went to take my car out for a drive. I live on a hill and my drive way is very steep. As I was going down the drive way I stopped to move some debris out of the road. To do this I put the car in park and put the parking brake on, which I rarely use, only because I was on a decline. Got back in the car, released the parking brake, and heard the worst metal to metal grind you could ever imagine. Immediately I knew my drive for the day was over. Turned around and parked back in the garage. I initially thought that the parking cable was stuck. There were no brake warning indicators on the dash. So I let it sit and tried backing up back and forth. No success. So I let it sit the weekend, and called Danbury Porsche on Monday. The sad part was, is that the car was just in on Wed for it's annual check up, oil change and filter, install of Fabspeed Headers, and a new front lip spoiler, along with a few interior accessories.

I sent PM to Dan aka Edgy on Saturday and he gave me some helpful advice. I called Danbury Porsche Dealership on Monday and they said that I may have a stone caught between my dust shield and my rotor. I don't think that's the problem. The bottom line is that my car sounds horrible when it moves; metal against metal sound. I seems that my parking brake cable won't completely release the rear brakes. They still seem slightly engaged. Please note that the parking brake lever does work. It has good tension and I can lock the rears when completely engaged. But how could that happen on a fairly new car and no warning displays? I know that it's under warranty, but it seems so odd. My real problem is that I'm having a hard time finding a tow company with a lift so I won't get my new front lip scraped. I'm in a tough dilemma. If anyone has any other words of wisdom please respond. Also if anyone knows of a great towing service in Ct. that will service Litchfield county please let me know.

Thanks again to Dan and everyone.

Sorry for your trouble. Hard to know what's going on but I will say that getting a stone stuck between the shield and rotor can in fact cause a pretty hellacious scraping noise. An inspection with a flashlight might be worth your while. Good luck.

Agree - jack it up and take the rear wheels off and give the brake assembly a good look over.

That happened to my old m3 but I had 10 yrs on the same e-brake pads. They crumbled and bits got stuck in between after parking on an step incline... I always use the e-brake when parked but rarely had to park on an incline here in Austin. Sounded awful so I had it towed to my indy vs. driving it there. Your p-car is new so this may not be the case unless the e-brake pads disintegrated on you somehow... very interested in the post mortem on this one.

Having the car towed Saturday. Will let everyone know the results on Monday.

I thought everyone used their parking brake as a "matter of course" when parking. Using the parking brake even on level ground provides a margin of safety and might also help protect the drive gear in the event of whatever...

Good luck with resolution of your problem!

If you have room and a jack, you could try putting up each corner and manually rolling the tire while inspecting it to see where the noise is coming from. It may save you a trip to the dealer if it is something simple.

Or, just have another person slowly move the car while you walk around it, listening for the offending wheel(s).

Problem solved. All I have to say is that Dan was right. Porsche flatbeded my car to the dealership today and Lonnie who usually works on my car happened to be there and was able to put my car on a lift and check the wheels. The left front wheel had a stone caught between the dust shield and the rotor. That was the sound. He handed me the stone and said I was all set. Drove her home without incident. Unbelievable. I couldn't see it when I checked this week because the car is so low. So that's it. No problem with the brakes. It just happened to occur at the same time I put the parking brake on. A lesson learned.

It's a good idea to use your emergency brake on a regular basis.... Not using can result in a sticky cable....

Glad to hear it was something simple!!
