I don't think the linked brakes work fine, and neither do a lot of others.  If you like them, I'm OK with you liking them, but I don't. 

Yes, trail braking uses the front.   Do you know what the separate use of the rear is for?

On the Gen 1 bikes, the ABS is separate on both brakes, and I use the rear brake to "back-in" the corners going downhill in the mountain twisties. Leave the gears in 3rd, cram on the rear ABS with no worry of a high side, and the bike 'settles' in to the next corner- very effective when boogying with a fat lady.

I'm not a fan of these linked brakes because;
I got into a corner a little to fast so I wanted to back-it-in just a little, I applied a little more rear brake but this is not the time to have something unexpected to happen but it did.
I was already carrying a little front brake when I applied a little more rear when the front end dived which as you know it changed the geometry and at the same time my personal exhaust valve change geometry too.
The last thing I wanted/needed at that time was more front brake at that lean angle, it all worked out but it scared the crap out of me.:yikes:
I have owned over 75 motorcycles and been riding since I was 12. I raced for several years but after 15 broken bones and other issues I quit. I don't remember the last time a bike scared me because of some trait that was unique to it.
I also get a slight bump in the rear pedal when stopping some times, does anyone else get this?

On the C14? Slow speed (parking lot, U-turns etc.) tight turn maneuvering? Still works for this on linked brakes below 12 mph.
.....and I personally use a lot of rear brake on dirt bikes in dirt, especially going down hill.

I try to use both brakes, even though I agree with Ted that just using the front is much simpler and probably equally effective for my skill level, just because I ride other bikes and none of them have linked brakes.
In my advancing years, I no longer trust that my brain won't use the wrong technique for the bike that I'm on at the time. Speaking of brain farts, I'm not even sure if that last sentence is correct,
triple negatives?  :-\

I really thought the linked brakes were going to bother me more than they have. I keep mine on the less linked setting. After a few rides, you get a feel for how much rear brake you can use before the front kicks in. Only time I really use the rear brake is scrubbing off a little speed entering a curve if I come in a little hotter than expected. That doesn’t happen very often now that I have a better feel for the handling and lean angle limits of the bike. Switching bikes between cruiser / bagger and Concours does mess with your entry speeds some.

Hi again P.  Good to hear your enjoying your new C14.  Fortunately for you, Kaw revised the calibration of the 'link' rear to front on your model, reducing, if not eliminating, the unsettling effect Gabriel experienced.

Another use is to tighten your line if you're running just a bit wide due to too much speed or the corner tightening up unexpectedly.  The front would help also, but at that moment,  I don't want more fork dive, because that decreases the fork angle (which tightens the steering a bit and lowers the front of the bike)  and more importantly (to me, anyway) puts more weight on the front when you may already have a lot on it and don't want to add more.

Check out this mod Gabriel for unlinking the GEN2 brakes. It is only recommended IF you are confident at working on braking systems.

Oddly I was never notified about your post?
This looks like the simplest solution.
Thanks
; I have to assume that this decouples the linked system from the rear to the front and from the front to the rear.
I have not looked at how the ABS pump distributes it's pressures so I'm going to assume it's down the same line. (coming and going)
Does this make sense?

Was there a part number list for this mod?

This (my) set up (in reply 136 in the link above) removes the R to F link but retains the F to R link.

For those that are uncomfortable using the nut-bolt-washers-&-tape method I initially showed to terminate the displaced hose, I posted a pic of an improved way to do so.  That particular hose was from a wrecked bike.  It is used on the 1400 ABS unit.

http://www.kawasakionlineparts.com.au/partFinder/fiche/kawasaki/2009/zg1400-1400gtr/brake-piping#ficheZone


It is also shown in the 2nd pic of the very first post by the OP of this thread:

http://www.zggtr.org/index.php?action=dlattach;topic=13655.0;attach=15486

The cross-over hose from L to R caliper should be from the earlier series 1 bike with ABS or if that's NLA, from later ZX14 bikes with ABS.  Note that this cross-over hose from ABS bikes is a different part number to non-ABS bikes and priced accordingly, apparently due to higher spec.

I saw your earlier post.
I will be glad to just dump the rear to front connection.
Thanks for your effort.
Is the hose part number 43095D? Hard to tell in some of these diagrams?

43095-0219 or 43095-0220 

One hose is about 25mm longer than the other, which is immaterial.

EDIT: I've not been 100% happy with the method I used to block the displaced hose.  Having given more thought to it and scratching about in my tub of left-over bit from other jobs I came up with this short hose fitted with a 10x1mm plug.  The hose is from a 1400 ABS unit.  In stock form it joins the long steel pipes that run under the tank to the ABS unit - but it's a spare from a wrecked bike.  This short hose with plug will replace the displaced hose which presently runs to the right caliper.  It's necessary to lift the fuel tank to access the front end of the steel pipe to fit the 'block-off' hose. This update gives certainty that no leak will ever develop.  Of the 2 bikes I personally did the 'bolt & tape' block-off to, neither have developed any seepage whatsoever after more than 2 years with that somewhat primitive 'fix.'

By loosening the plug, air and fluid will escape past the thread.  When the plug is tightened it seals against the inverted flare within.
