"Take a look at the thickness of the hanger - if it's a less expensive stamped piece, you might try a thicker part. Also, pay attention to the fit of the ferrule on the cable end. If there's movement there, that will tend to exacerbate it." Happy to try, Ray (and I apologize for any imperfections of language in advance): The cable and housing connect directly to the cable hanger. The cable hanger is sandwiched between the nuts on a traditional threaded stem. The contact point of the housing end to the hanger is an inch or so away from the base of the hanger. As additional force is applied at the brake lever, there is a potential for the hanger to flex downward toward the front tire. As the hanger flexes downward, it releases a very slight amount of cable tension with respect to the brakes themselves. This causes a micro-release of the brakes, and a resultant un-flexing of the hanger, which retensions the brakes. Cheaper hangers tend to be a stamped piece of metal which flex more. I've also seen ferrules grind away at the hanger, ovalising the contact area (ferrule on the cable end should fit firmly into the stop) or enlarging it so that there is a slight amount of play. I was really discusing two variables at the hanger - both the physical construction of the hanger itself, and any movement in how the cable housing is secured into it. hope that makes sense, - Jim -- Jim Edgar cyclofi...@earthlink.net Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Your Photos are needed! - Send them here - http://www.cyclofiend.com/guidelines "I threw one leg over my battle-scarred all-terrain stump-jumper and rode several miles to work.
