Been having a devil of a time with my mechanical disc brakes. They are so fiddly to set up!! Two problems:
1. The instructions say get the caliper position by clamping with the brake lever- doesn't get close. I positioned by eye in the end.
2. The brake lever doesn't get anywhere near enough pad movement- one finger braking this is definitely not! I've got something useful after hours of fettling and going a little off piste- I partially closed the brake then tightened the bolt that holds the brake cable inner. Seems a bit dubious and certainy not in the instructions!
Had anybody else had this much bother with their Avid BB7s?
