Does anyone know the minimum thickness for the front brake
rotor on a 2005 base 997? I plan on replacing the pads but not sure if the rotors need replacement. Thanks

 

I believe the minimum thickness for the rotors is stamped somewhere on the caliper.. hope this helps.

 

I think it is stamped somewhere on the rotor, not the caliper.

 

I don't think you have to worry about the absolute thickness of the rotors. It's very unlikely they would wear down to a point where they would need to be replaced without exhibiting a variety of other undesirable symptoms much earlier. Rotors need to be replaced when they are cracked, heat scored, have spiders running between holes or slots or when they have worn unevenly and pull, shimmy, or exhibit other funky characteristics. So, if yours don't fall into one of those categories and/or you're not replacing them for peace of mind on the track, they are probably fine. That said, your car is 5+ years old and we don't know it's mileage. Depending on that, you may want to consider replacement as part of a reasonable PM program.

One final thing when they do need attention, do not waste your money to have them turned, spun or otherwise re-manufactured. It doesn't work for a Porsche or on other high end German cars. They will only last a short time and and the problems will reappear. Just bite the bullet and get some new ones. Hope this helps,

 

True, however there is still a minimum rotor thickness that has to be maintained. The tolerable wear is not that much, and may be reached long before any physical signs of failure are evident. I would not use age as a determining factor if the rotors are not showing any abuse and the wear is within tolerance.

 

Thank you all for your input.

 

I looked all over my rotors & calibers but couldn't see anything. Can someone, please advise more specifically where the information is stamped?

BTW, I have an 07' 997 C4S
