Remove the ABS from the back brakes - make up a new pipe linking the master cylinder directly to the back brakes, but what do I do with the ABS pump?

See the very first post of this thread.

It should answer your question on how to plumb the ABS pump so that you will still have ABS on the front, but not on the rear.

Yes you can, but should I put them here, don't want to hijack the thread?
Here's one anyway, Trike, Mrs and the dog.

Hi, yes I think that is the way to go to solve the ABS / linked brakes problem.
I still need to sort the traction control issue, the only way I can see which also keeps the front ABS is to make a new disk and mount it on the front of the diff.

I was also looking for some information on this linked brakes issue. I really hate this stuff so much that it makes me want my 08 even more. I think the ABS is very valuable, didn't have it on my 08, but the linked brakes trying to do what i can do better with less front end diving, is not making me happy.
I just can't get used to the fact that when I'm trying to get a smooth stop with my wife in the back, all of of sudden, she bangs helmets with me and the front end dives.
I like to have full control of my brakes... thanks kawy... There are also those times where you may just want the rear brake...

I'm wondering if by now someone has figured out a better way to do this and keep the ABS without any linking?

Make sure you have it set in the lightly linked mode and not the highly linked mode.

There have been no other success threads or used methods other than replumbing as described in this thread.  It is a shame, because a simple software alteration could allow it to be any amount of linking desired, including a selectable (and sticky) disable option.  But no such patch exists (that I have seen, anyway).

I unlinked mine as Randy suggested a long time ago.  I lost ABS on the rear, I could give a sh*t. No problems with it whatsoever.  I freaking love it. Now before you get all worked up about (fill in the blank), it's my bike, my time and my money.  I'm happy, hell no, I'm ecstatic with it.

I did it because I don't want the damn computer changing its mind mid-corner and suddenly, I get a bunch of brake dive when I'm already 'fully committed'.   Or having to brake one way on one of my bikes and a completely different way on another.  I heavy brake and trail brake with the front, no rear. I use the rear at low speed and to tighten my line in the corner. 

Did I mention I'm happy?

Just read that Kaw article, note this:

" Based on the vehicle speed, K-ACT decides the optimum hydraulic pressure to send to each caliper, ensuring that even with a heavy motorcycle, stable braking performance is possible."

What that seems to have done to me is, as speed lowers (because you're braking, duh), it changes the pressure to the respective calipers and you get chassis movement/transition that is not based on your inputs.  I don't like that.

Someone here or elsewhere said they had done it by blocking the ABS port to the right (linked) caliper and fitting the gen 1 hose from right to left caliper.  That way they had ABS as per gen 1.

I am very interested with the linked brake fix discussed on this post. Unfortunately this post has been dead for a while.

Hoping to see some updates on what is working and in particular what is mentioned in the quote above.

Yes, me too.
I didn't know this fix existed.
Will do a complete read thru tonight.

Ride safe, Ted

That's basically the same theory that I have. I was just wanting to use a "Y" block near the ABS Pump to connect the front callapers to the ABS Pumps outlet for the Front Left Callaper. I'd still have a short (8"-12") rubber brake line coming off of the ABS Pump outlet for the Front Right Callaper, but it wouldn't be connected to anything, but it would have a bleeder installed so that you'd be able to still fully bleed all of the air out of the system. I also "believe" that with this setup, when you have the "Low" brake selected, the front & rear would be un-linked, but when you had the "High" brake selected, they would be linked.

Now, like I said, this is just a theory as I haven't done this and if someone does do this, they are doing it at their own risk.

The 2015's supposedly have improved, lighter linked brakes. I was wondering how much better are they? And weather or not this is just software or different hardware? Which then begs the question could this be retrofitted to older ABS bikes? Enquiring minds want to know.

I am curious too (just academically... I don't think the low-linked mode is any big whoop before).

I am pretty confident it is 100% software.  It is a simple program change

I already speculated about that in other threads.  I see no reason why such a change couldn't be ported to the other bikes, if it is something that COULD be programmed through a shop computer.  That doesn't mean Kawasaki would make it available, though.  And I doubt they would.  I am not sure if that functionality was meant to be updated, so the firmware might be fixed.

Don't have a 2014 or older to compare, but I can tell you my 2015 front calipers are fed by the same brake line, with a 'Y' between the forks. And similarly, just one brake line to the rear caliper. So apparently there was a hardware change too, if older ones were not like that. I HATE not having 100% front power with the lever, like Honda does. At least now, the brakes are linked electronically only. But not ideally, nor fully, like on modern BMW bikes, where the front lever provides 100% front & rear braking power (including a proportioning valve), and the rear only the rear.

The Connie has 100% FRONT braking power with the lever, but not 100% at the back. I think it's 50%. And I doubt it's 'intelligent' enough to be proportioning, but don't really need that on a sport-touring bike IMO, especially if riding solo. But it might have it. Somebody with a passenger can play with the brakes and find out easily. Solo, I feel no difference whatsoever using both brakes (as expected), from just the front... which is what I always do. I've been looking everywhere for specific info on the brakes, but just couldn't find ANYTHING. Anyway, the pedal has 100% power for the rear, and I believe 20 or 40% at the front, depending on linking setting (2 available- low and high). So just the rear pedal would be dangerous folks, as braking distances would be tremendously longer. As you should know, the great majority of braking is at the front, and that's why you have 8 pistons and 2 big a$$ rotors, vs 1 or 2 pistons and a puny rotor. Besides, by only using the front brake, in case of an emergency in a non-ABS bike, you'd be much less likely to inadvertently lock-up the rear wheel and end up on the ground. Believe me,  modulating the front brake alone is enough even for an experienced rider. And on bikes with linked brakes, makes no difference to use the rear pedal, so no downside to just use the front lever. But to each his own. But yes, with ABS, you can do whatever you want... but just make sure you're capable of invoking ABS (100% braking power) with the front lever, or you'd be wasting precious real estate in an emergency. Practice folks.
