Brake rotors

Recommended Posts

Can anyone tell me why the rotors on my 2002 996 C2 with 16k miles on it are cracking / checking? I have hairline cracks spreading out from the drilled holes in the rotors. An indy told me when the cracks "join up" or run out to the edge of the rotor, it's time to replace them. I've looked at a lot of friends' Porsches and no one else's is doing this, several with 2 to 3 times the mileage. Can anyone shed some light on why this would be happening with so few miles?

Thanks much!

I've only owned the car for 2,000 of its 16,000 miles and they just started to appear. I'm about as anal about my cars as you could be, so I know it's not a heavy foot or unusually high heat. I thought that's why they cross drilled them anyway - to help dissapate heat. So far in my ownership I've been more impressed with my BMWs I've owned in terms of braking power, feel, and durability. This is disappointing to say the least. It's a great car and I love to drive it, so I'll obviously replace them, but it's too bad they don't last longer.

Thanks for the input.

X-51,

Sounds to me as if the previous owner may not have driven the car tha toften, but when it was driven it may have seen some track time. If you google search "cross-drilled brake rotors" you will see a lot of info regarding the pros and cons of crossed- drilled brake rotors. another "no-no" with crossed drilled rotors is NEVER wash the car when the rotors are hot but rather wash the car when they are stone cold. Enjoy the new P-car!! B) Demosan
