I have noticed that through the travel of the fork, the v-brake changes position in that it pulls more from one side then the other, but this changes as the fork compresses so that the other side then pulls more. This leads to brake blocks rubbing when the suspension is active. I know I could change to disc brakes but I have a lovely set of lightweight Deore XT Vs. It appears that it might be connected to the changing position/length of the brake cable as the forks move. Has anyone else noticed a similar problem?
