The service manual doesn't give ANY details of the inner workings of the ABS Control Unit. The only way to find out is to take one apart. I've been looking on ebay, but all of the ones that I'm seeing listed are for the 08's & 09's.
Ok... I've been thinking about this issue some more.
I’m thinking that if you tie the two lines at the ABS unit that go to the front brakes together with a "T" or "Y" fitting. Then tie from the other side of the "T" or "Y" fitting to the front port of the ABS unit and block off the 2nd port for the front, you "may" un-link the breaks AND still have ABS to both wheels. The reason I think that the second port of the ABS Control Unit from the front of the bike should be the one blocked is because that port isn't there on the ABS Control Unit of C-14's that don't have linked brakes (2008-09 ABS models (can't remember if the linked brakes started with 2010 or 2011?)). My reasoning behind this is I “think” that one of the lines that feeds one of the front calipers is common (fluid path wise) with the rear.
Now this may only unlink for what is called the low link setting (less aggressive setting) as the high link setting (I believe) sends fluid to both front calipers when the rear is applied.
Anyway, this is just my theory and without having an ABS Control Unit out of the bike to look at its inner workings, it's only a theory.
That's a very good theory, at least to unlink the front when applying the rear brakes. Since the '10 and newer only apply pressure to the right front calliper when applying pressure to the rear, that "should" remove it from the equation. I can vouch for that last sentence because my right rotor is thinner than my left rotor, probably because I've been running in "High Combined" mode exclusively for the last 25K+ miles, and I *use* my brakes.
As for unlinking the rear when the front brakes are applied, I don't see how this would solve it, but since the rear doesn't seem to be as obnoxiously linked as the fronts, it may be acceptable.
This is a worthwhile enough idea, that I'm going to look around and see if I have the parts. I hate opening up the brake system (due to the chance of introducing air bubbles that don't want to leave), but like many, I dislike the linked brakes even more.
After reading this last night, I was wondering about simply using an ABS unit from an 08/09. Has anyone looked into that?
