Can anyone help me out with a problem. I needed to change my rear pads. When I was about to install the pads, I had to compress the piston into the caliper. Right after, I had to replace the clutch cover. In order to access on the the bolts on the clutch cover, I had to push down on the rear brake pedal. When I did this the piston in the caliper started to come out since there was no resistance due to the rotor no being there. After I pushed the piston back in, I reassembled the bike and tried to use the braked. When I push down on the pedal, it had no effect on the piston, it does not move out at all. I added enough fluid and tried to bleed the brakes. Still no movement out with the piston. So I took the wheel off again and pulled out the piston to see if I could see a blockage in the fluid outlets in the caliper. When I pushed on the brake pedal, it pushed fluid through the outlets that should push the piston out. I can seem to figure out why the piston wont move out though. Im starting to get annoyed and rode all day today with no rear brakes. It sucked! Does anyone have any advice. Sorry for making this so long. I am just real frustrated. THanks in advance!
