hey mate, before you go spending money take it all apart, take the caliper off the forks ect, take it completely to peices, give it a good clean out, make sure the pads are pushed right out with a screwdriver, give the lever a clean out, and give the rotor a good scrub in a sink of HOT water and then rebuild it. andy ball had the same problem so we took it apart and spent a good hour cleaning it out and after that it had never worked better few bottles didnt go a miss either hope i was some help ..rob..
