Hey all you mechanics. I seem to be having quite an issue with the latest additions to my project.

I routed up the rear brake cable today (mid-80's Nishiki, so along the TT) and it seems that there's a lot of friction in the set up. If I press down on the lever and just release my hand, there's a slight delay in the cable being pulled back to its resting position. If I snap the brake lever, then there is no delay.

It's a DiaCompe aero lever with the old, specialized ferrule. The rear brake is modern-ish Campy Veloce, and the housing is unlined and thus the brake cable was greased prior to installation.

So...why am I having issues? As far as I can tell, I cut the ends square and there are no issues with the cable itself...
