I purchased a Bosch system and a harness made by Sakata. Brian Sakata even returned my call after hours to answer my questions. Love personal service in this industry! I'll be driving without ABS for a couple of months then install it. I'll report back on how it goes. Anyone know if ABS will be in the 2013 Cup?

I'd appreciate some help here please.
I've just competed in an enduro race in NZ in atrocious wet conditions driving a 996 Cup car.
I took over at 1 1/2 hours, and at nearly 2 hours, without any warning, at the end of the back straight when I hit the brake pedal, it went all the way to the floor. I pumped it twice without effect by which time I was a passenger heading into the tyre wall. I hit it hard. Very hard.
Whilst composing myself in the car, on top of the tyre wall, I checked the brake pedal and there was pressure there. WTF??? Back on parc ferme there was pressure there as well.
My engineer reckons I either aquaplaned or it grabbed and turned around when I hooked 4th. These are reasonable explanations for such an incident but do not match what I remember and the data [the latter is not clear cut, at least on initial inspection].
I distinctly remember the brake pedal going to the floor twice and that horrible realisation that I was in big trouble. I am sure I did not change down a gear.
The data shows initial slowing of a wheel sensor at about 50% of the rate of the previous lap which then flattens out followed by a '100% throttle blip' [all the rest of my blips are around 20-30%]. The rate of wheel sensor slowing then exceeds what is possible mechanically.
I think this reflects possibly some initial braking [less than normal] followed by complete loss of braking and the pedal going to the floor with the edge of my foot catching the throttle on the way to the floor.
But why then do we have pressure in the brake pedal afterwards?
I can accept it if I have made an error, or just aquaplaned, but it doesn’t sit right.
Anyone heard of a similar incident of complete loss of brake pressure, but with pressure returning seconds later?
Any insight will be gratefully received.

Did the pedal go to the floor? or to the bottom of the normal travel with no effect? The latter is "ice mode". Going soft to the floor is a different issue altogether. if you had a firm pedal after a few stroked of the pedal it would be suggestive of serious pad knockback. With a wet and bumpy track you could of had a combination of both issues.
Sorry for your incident hope it's not too bad.

Ok fellas - I completed two races without the ABS. I adjusted the MOTEC so it would show brake pressure to give me more feel/insight to where the lockup would be. Smoked two sets of slicks This week I'm having the Bosch ABS installed. I mean really at 2-2.5k a set of tires. I understand the pure skilled racer mentality, no question you are studs and better drivers. Is it bad to to it for the cost of the tires?. If you want to push hard on the limits and everyone else is running with it - what to do? Will let you know hoe it evolves - expensive option no doubt!
