Finally decided to ask for some advice about this. My back brake is not releasing right. When i pull the back brake, one side releases the other doesnt. I have cleaned the pads incase it was something on there, wiggled everything around, tighted up the cable, this made it better, but it still just catches on one side. I was going to take the whole thing appart, but i cant seem to get the bolt un-done. I get the hex key in and start to put pressure, and it just wont budge. I've put some oil on it, to see if that will help, but so far it hasnt. It isnt the spring, because i have already checked that. The only thing i can think of is to undo the cable, and widen the distance between the pad and the wheel, but i'm not sure it will help. What seems to happen is when i pull the brake leaver, the cable that goes along the frame goes tight, then when i release the lever, the cable just goes really slack. It happened when i was on the club ride, it was ok when i went into the cafe, but when i came out and started to go, it started it then. The bike did get alot of dirt on it, but i have cleaned it up as much as i can, but it still does it. Any suggestions?
