The info i was in search of is the piston size it has as thats what Zeta was referring to..........edited for knotted knickers.

OK. Since my last answer seemed to rankle (wasn't clear to me as to what you were after, BD. Just tryin' to have some fun.), I'll try to make good. If the M/C is marked with 3/4, it should be a 19mm unit.

Well just completed a long weekend of riding on the new 05 636 and all I can say is this bike has the brakes the 10R should have had. Even with stock lines this bike stops like a race bike and doesn't do a bad job in the handling department either.
If the new 06 10R heads in the same development direction as the 636 it should be very interesting to see the end result, handling wise the new 600's are a mile ahead of the current 10R machines.
If you get the chance to test ride take it up you can't help but be impressed.

Latest information on the brake front. I have now changed the master cylinder yet again to a 18mm x 19mm item but still a Brembo item with different ratio lever to get the feel just right.
This is the same setup we will be running on the Superbikes as our first test session showed big problems in the braking department even with the ZX7RR masters after 3-4 laps no brakes.
The shipment is supposed to be in this week have, ordered 3 to cover our needs and will start testing in the next session after some suspension setting changes and engine mapping as the season is fast approaching and still have three bike to build yet.
I will post the final spec on the complete setup after the next test session as we will also be testing pads as well so this should be the ultimate brake setup on a 10R using stock callipers and rotors to meet Superbike rules.

EXCELLENT! I almost can not wait to see your results, but obviously... I will have to wait until then (or do my own testing - which is beyond doubtful).

No problems you will be the next to know after me! I will also supply part numbers that should match those on your side of the World, hope to schedule the next test session within the next 2 weeks parts are the current biggest holdup.

3/4 is a 19.05mm piston pump. I just fitted one to my zx12r that comes with a 5/8 = 15.875mm or 16mm, when you compare m/c you have to compare apples to apples, you cannot compare radial to convencional the radial will give you better feell even the same mm, wy because the distortion betwen lever travel and force is less.
I just fitted my zx12r with a 19.05 or 3/4 pump nissin
http://braketech.com/cgi-bin/search.pl?conditions=Make,Part_Group&Part_Group=nissin&partialmatch=1&template=nissin&sortby=Make,Models¤tpage=2&resultfrom=20
the first thing I noticed its the linearity betwen force aplied and braking force, 2nd its the less effort beacuse the 3mm diference in piston.
I wonder what Kawa had in mind when fitted a zx10r with so small pump, maybe the 14mm has way less travel and compensate.

Marcos, all other things being equal, a larger piston diameter (19mm) moves more fluid with X amount of stroke. But since the pressure on the M/C is spread out over a larger area, it would require more effort at the lever to create the same line pressure. The smaller diameter piston (14mm like the ZX10) moves less fluid per X amount of stroke but since the lever pressure is exerted on a smaller area, you can achieve higher line pressure with less lever effort. But, the lever would have to travel farther to move the same amount of fluid as a m/c with a larger piston. I think the differences you noticed are a result of the M/C design. And possibly the lever pivot ratio.
