Yes, that link I posted appears to be for the z 1000, 14 to 16. I have no idea why it would be different than I have, but it's an extra 30.00. I'd be afraid to try the one I had due to returns being such a pain. The bracket is a well made, precision piece, so I do trust them as far as fit goes.
I bought my caliper here: Brembo P32 Brake Caliper
The master cylinder is from a 2008-2010 zx10r. You about have to stay with those years for the 1/2 size as oposed to 14mm. I paid 9.99, on eBay. You could also try our stock 14mm master cylinder we already have on the bike. It worked, but the feel was not quite as nice with the smaller diameter mc. The 14/34 combo felt mushy... ,just what we are trying to get rid of..but was very powerful.
It was horrible to bleed. Seriously, I've bled brakes on the car, truck, atv, motorcycles, etc and never had an issue. This was rough. I finally ended up using an air powered bleeder and it was good within 10 seconds...awesome.
If I were keeping the stock rear master cylinder, it might work better with that p34 size, 34mm piston. I'm giving you the short version of what I tried. That 1/2" master cylinder and 32mm caliper piston is the closest match I could find to what brembo sells. Brembo pretty much sells only 13mm rear master cylinders. So, the closest I could get to that 13mm, without big money, was the 1/2" (12.7mm) on that specific zx10 series.
I hope you do this so we can compare notes. My thought was to dial in the feel, then use brake pads to work with the power level, later on.
