RS685's. RT99 rotors.
8070 Calipers. L02A pads.

Most of the Calipers could be recovered. nearly all rotors were 140mm. All experienced heavy warping.

Where were they being ridden?! I have been using an rt99 on the front and an rt86 on the rear for the last 2 years, no issues at all, using the rs785 sytem with finned pads..

Does it matter? Will it justify brake fade due to poor heat dissipation?

The bikes running 160 up front of all Shimano levels didn't fail. 140's on the same brake setup did. Not all, but enough to raise questions.
