The rear v brake on my bike does not release properly. The side where the cable housing sits does not retract from the rim. The side where the inner cable attaches works properly. If I remove the cable housing from the arm there is plenty of spring tension there and it fully retracts. I have greased the mounting point on the braze on. I have tried adjusting the tension with the adjustment screw but it does not solve the problem. I am thinking that I can probably change the position of the spring on the braze on to a hole that will provide more tension on the not working side and to a hole that will provide less tension on the working side. Is this ok? Can anyone offer another suggestion as to what to try?
