Welcome to PCA's source of expert advice, where our PCA National Technical Committee experts answer your questions about all things technical.
Is there a special Porsche tool to disconnect power steering lines? I've found the link, bought new hoses, but don't see how to disconnect the hose under the car (not the steering rack, and not at the reservoir and pump end) Thanks.

READ ANSWERRecently purchased a 2011 997.2 Carrera S. Has 66,000 miles. Needs new rotors and pads. In looking at FCP euro and Pelican Parts, I, of course see Porsche OEM set, all four rotors, at about $1300. I also see Sebro cross drilled at about $614 a set, SHW at $576 per set, Simmermann at $703 per set, and slotted Sebro set at $737 per set. I prefer slotted, in general. Does anyone have experience in any of these other name brands.
Wednesday 07/16/2025 | 2011 | 911 Carrera S | Brakes
Anyone have experience with using Sebro, SHW or Zimmerman brake rotors as replacement for original Porsche rotors. I understand that these name brands at some point supplied Porsche in the past. That doesn’t mean necessarily that these aftermarket rotors are still at those quality levels. Also. Anyone have experience with Brembro Ceramic brake pads? P65011N and P65014N ? $65 and $64 seems really cheap. Looking for good, maybe better than stock, ceramic pads. Like the lower a ...
