Nice to talk to you all again. I've been refurbishing a classic women's city bike for my girlfriend (vintage French - the bike not the girl ;) it's shaping up groovy. The primary problem I'm encountering is the brake calipers. They refuse to stay centered. I adjust them so the pads are centered and equidistant from the rim and on the first pull of the brake lever everything seems to be ok. Two or three pulls later one pad (specifically the one opposite from where the cable is fastened) remains on the rim, while the other continues to move freely. Part of the problem is that the outer housing of the cable has some play aka doesn't remain static. However I notice upon visual inspection that one calpier (the one that becomes stuck on the rim) simply doesn't move as freely/ an equal distance and the other. I've tried adjusting both the hex nut from behind the brake stay as well as the outer nuts with little success. Short of simply replacing the whole mechanism, is there something I'm missing here to solve this?
Ps tried uploading a photo I took with my phone but it was to large for the text box does anyone have a quick fix for that as well?
Btw the bike is a late 70s Peugeot
Again thanks a lot for any input and happy roads :)
