I just got a new CX bike with Avid BB7 mech. road disc brakes which I use for both commuting (very steep fire roads) and non technical trail riding. The brakes stop pretty well concidering the pads are not bedded in just yet. Originally the brakes were mushy and rubbed the pads. The shop I got it from changed out the housings to Jagwire and put longer screws in the spring tension part of the brake. They told me to ride it for a couple of weeks and the rubbing should go away. This helped the rear brake quite a bit. The front still "tings" when standing and worse when under heavy braking on a really steep fire roads the pads don't retract and it rubs heavily and makes this sort of grinding noise for perhaps 30 seconds after I release the levers. I'm pretty sure this is not normal. They work fine for normal road riding. I have Avid Juicy 7's on my mtn. bike and know them pretty well. Anyone experience this? Do you think a quality cable set like the Jagwire racer cables or perhaps the Avid full metal jackets would solve the problem? Do you think somethng is wrong with the caliper? Suggestions?
