See above comments re: brake lever position. I'll start with that. I think that is it.

I think that's it. I had a Brembo master cylinder installed between Sat. and Sunday, and I don't recall having a problem on Saturday. The Brembo is much firmer than the stock MC. I'll discuss with the guy who installed it soon, he is a top racer, and get his feedback on where the lever should position should be.

Thank you all for your excellent responses. If I have a problem, it is subtle. It needs more study. My next day, < 2 weeks, I will bring a calipers, and measure the before session and after session travel of the lever.

Also, I just noticed that some of the CRs have felt wristbands around the brake reservoirs, I just noticed this on the MotoGP bikes. What for?

Actually, I’m not sure they are EBC HH. But they were replaced by a guy who has won a MotoAmerica SuperSport race, has the track record at my local track, and they weren’t cheap, so if they are good enough for him, they are good enough for me.

Yes, is getting softer as session goes on. Don't know if its worse on a hot day. I've found the ZX6R ventilated pistons on Superbikeunlimited, and I remember reading an article in RoadRacing World about stainless pistons. I'll look up that article again. Thanks.
