Interrupter brake lever cable routing

I installed a set of interrupter levers on my touring bike last night. I am running into a problem, though, that I can't seem to find a way to route the cable that when I pull the back brake, the front doesn't actuate. Is there some special routing that I can't seem to figure out, or is it just a reality of limited real estate on my particular bars? It isn't especially problematic, I can't see a situation where I'd only want to brake with the rear, just would like to clean it up if possible. As you can see, I purposefully angled them a bit different to minimize the action.

These are pretty nice, though! Great to have full stopping power on the top of the bars!

Some pics of the current routing:

Not sure I understand or see the problem. How is the use of the rear brake causing the front to be actuated? That would imply the rear's cable housing is somehow pulling on the front's cable, but I don't see how that would be possible in the photo you have provided. Can you explain further where the cable is interfering with the front brake?

When I pull the lever for the back (left in picture), the cable is being pushed forward into the cabling for the front (right in picture), pushing it forward and actuating the brake. I'll try to grab a picture of the problem at lunch.

Ah, I understand now. Try routing the rear's housing in front of the fron't's housing; that may solve the problem. You also may need to make the rear's housing a little longer.

Need re taping the bars , but, try putting the levers at a different more natural angle,

lower and make your rear not touch the front.. put it in front of the front cable..



Perhaps, adding a V brake noodle, right at the lever, will let the cable bend down sharply but still not add significant friction..

to miss each other entirely.

It is just temporary hockey tape so I didn't have bare bars, I haven't put the real tape on it yet fully expecting there would be some control adjustment.

I tried looping the rear way out front of the front, I just think there is too little real estate where the cables come into the handles. There is only about 3" between the ends of each lever, that is where the issue is. As to putting the rear in front, then I just have the opposite problem, and I think there are more situations I'd brake with just the front than just the rear.

I'm not quite sure what you mean by a more natural angle, though.

when I lay my hands on the top of the handlebar, riding, the top mount levers are under my fingertips . \

when I apply the rear brake, the center-pull cantilever brake housing ferrule,

.. in the headset stack mounted, Brake housing hanger just moves sideways a Little .

(I just looked)
