2nd Gen Master Cylinder

Ok, before I get hammered about previous threads on this hugely covered front brake sponge issue, I'm on my mobile while at work trying to find my answers and can't search with blistering speed. The issue I have is this: I did the 2006 CBR 1000 Caliper upgrade with new pads and SS Hel lines and am still pulling my LEVER almost all the way to the clip on, so apparently MY issue is in the Master Cylinder. NOW, if I upgrade, what master cylinder is better and used the same levers? Since I shelled out the $150 for my Gold CRG levers? If I have to I can always sell the Calipers and go to the Nissins, but I'm trying to conserve some cash for other stuff.. Any input?? Thanks ahead of time...

What year ZX10 do you have? The Nissin radial MC that comes on the Gen 2 and 3 is pretty much the way to go. If you already have that, then it sounds like there's something else wrong with the system. If you have to upgrade to the radial MC from the Gen 1 then there's no way to reuse your levers. Completely different setup from the linear to the radial master.

I may not be perfect, but at least I don't ride a Suzuki.

Yup. If you have a gen 1, the best thing to do is the Nissin Radial master from the gen2,3 etc. There is nothing wrong in the design of the Gen1&2 Tokico 4 pad calipers. I don't care how many posts you have seen with swaps and other BS. My shop has done countless Gen1s to Gen3s. The issue is either air in the system (95% of the issue) or a bad caliper/bulging line.

I have had bikes in here that have had several brake parts swaped out to get the thing working, but until we did the bleeding (a process, yes) the lever was spongy. Also, get rid of any stainless backing shims beteween the pads and pistons. Also, never tighten the calipers to the forks unless the brakes are engaged and the front wheel is in forward rotation load position.

Yeah, its a 2nd generation (2007) and as I said, its got new ss lines, the cbr conversion calipers, but I have a mechanical bleeder and its been bled methodically. As a matter of fact, it was bled the same as a CBR and two Gixxers I do maintenance on. And the brakes on those scooters are flawless. So if there's a trick, ie something only mechanics know, wouldn't that be kinda ridiculous and at some level a liability? Either way, it is of my opinion that the pads are good! The calipers are good! The lines are good! And I think the MC is junk! Radial or non-radial.. The reason I think so is because the MC forces the fluid through the lines to force the piston cups out towards one another sandwiching the rotor causing friction resulting in the wheel to stop, I think we all agree to this point. But as you pull on the lever, you can feel dead space for a good bit (which I admit, could also be misconceived as air in the line). But all of a sudden the brakes bite! Also what baffles me is that I can pump on em a couple of times and reduce the dead play in the lever. Again, this would suggest a bleed issue or air trapped somewhere in the lines or calipers. But why do none of these issues arise with the other bikes I mentioned? Only part I haven't changed is the MC and it seems everyone is swearing by the calipers, so...I don't know.. So if I am missing something, please educate me. By the way, my lines double off the MC and Single to each caliper instead of single out off the MC and split off the right side caliper!

Have you bled the MC properly? I'm assuming you have, but just want to be sure. There's a bleed nipple on the MC itself and that should be bled first before doing the calipers. Even if you're using a vacuum pump, you need to bleed the air out of the MC manually or with the pump. I'm not sure if the other bikes have this sort of MC or not so that may be the difference.

The OEM Nissin radial MC that comes on the Gen 2's and 3's is very good. If you're having problems, then I'd look into the used calipers you got as an issue if you bleed the MC and still don't get positive results.

I may not be perfect, but at least I don't ride a Suzuki.

I bled the MC, however I didn't bleed it first. I have ran across a great step by step set of directions from the WERA forum and am gonna give that a shot tonight. It makes sense that you can't get a proper bleed unless the MC is bled first. Will update ASAP. Thanks for the help..

You may have just made a "lateral" move with the caliper swap on your 2nd gen though....on the 1st gen the brakes were bricks plain and simple!! on the 2nd gen i thought they upgraded a few things and one being the MC going to the "radial" unit. i've read a ton of different threads and posts regarding the caliper/master cylinder upgrade from the 4 pad setup to the 2 pad,using cbr calipers with 5mm spacers, zx14 or zx6 calipers...the list goes on and on. get all the air out of the lines and you should be good to go, i own an 04' so i've been thru my fair share of brake swaps and upgrades...........best of luck and drop an update to let us know how it turned out?
