Pad Deposits or...?

Cyber370

I wonder how much of that is due to the fact the discs are slotted?

I talked to some Z guys at a track day yesterday (which was a pleasant surprise, since there are rarely many Z's at our local MI tracks). One, who is using the same combination XP10/8 said he was experiencing the same issue with deposits on the rotor. He contacted Carbotech, and they said it was due to excessive heat. He installed some simple brake ducts and the issue went away.

Another guy who was also running the same combo XP10/8 for the first time started getting deposits mid-day and was getting some vibration too. Braking performance was still there. No brake ducts.

It has been years since I ran Carbotech, but seeing and riding with the one driver getting vibrations made me remember experiencing the same in my Z. Might want to look into ducting or a different combo if the issue persists after cleaning the rotors up and re-testing.

I use Hawk DTC-60 front and Performance Friction PFC-01 rear. No issues with heat during my 20-30min sessions and rotors looking spiffy. Good luck.

You have a ton of heat checks (micro cracks) in those rotors!

Might look them over closely...

I know, i saw them too. Not too much more life in these rotors. Thanks for looking out

Surface cracks, like those, just need to be monitored. They don't mean the rotor is significantly damaged or needs replacing soon.

Yes, I should have further clarified in my reply. Due to the rotor thickness - they do not have much more life in them.
Thanks again though. Good to have this info in the thread too.

Good question..i noticed that theres much more deposits right after the slot. Like it shaves a bit off and then those shavings get baked right on.
