I have an issue with my rear break caliper, basically summed up in that it does not return to a fully open position after realeasing the brake lever. I talked to my LBS about it and they recommended to check cable for rust, particularly around the housing. I did, found some rust and sanded it off. Brake is a little better in that it does not stay rubbing the rim; however, still not coming back to it's starting position. Should I remove the caliper to clean and lube?
Also, I don't think the cable goes back on with too much tension....rather, just not loose?
Thanks for any advice!
