Got the axle back in yesterday after replacing the bearings and seals. Chain and sprockets replaced and Finally got around to trying to bleed my GSXR rear brake today. I read several threads on bleeding them and tried several different methods with no success. I can pump the pedal several times and crack open the bleeder valves (one at a time) and I get fluid but the pistons are not seating the pads on the disc. The system was shipped to me empty when I got it and I replaced the line with a Polaris Braided Stainless line. Any hints or tips? Had the same problem on the front YFZ brakes until I pushed the pistons back into the calipers. Then they bled easily and I have done this on the GSXR caliper as well. I would really like to do this with out buying a pump but will do it if I HAVE to.
