Well, that’s confusing since you show a Sugino crank in your pictures.
I’ve had the group for a couple of months but I couldn’t find a rear brake that would work. I tried Paul Mini Moto’s then Paul Touring Canti’s none would work. In a bit of frustration I bought some Rene Herse canti’s they work sorta.
I’m not sure I want a bike that has in essence a drag brake in the rear and a powerful brake in the front to ride a lightish touring bike even if I like it. In the end it stops and goes but….
A couple of things I see wrong with your current cable routing. First you really should use the cable anchor point on the frame if you have one. See the red arrow below. It’s much more stable. Your current anchor (red x) is short which makes for a longer cable run outside the housing which can be more flexible.
The Surly hanger on my bike below is much longer which allows for a longer run of the cable housing as well as a straighter run. My bike doesn’t have the cable anchor on the frame but I don’t have any issues with the rear brake being highly effective everywhere I ride.
You might also want to consider replacing the hanger as well. The Paul’s Moon Unit is nice and wide which makes for better leverage of the cable on the straddle cable. Additionally, shorten up your straddle cable significantly. A long straddle cable makes for mushy brakes in my experience. Combine that with the hanger and your brakes are going to be rather ineffective.
