| The slave will be full of air too. With it off the bike, open the nipple, push the piston in as far as it will go, tighten the nipple and release the piston. Do this 2 or 3 times and hopefully you will get there. Once the piston starts to move I found it useful to release the nipple with the lever held in. The clutch pushes the piston back and purges the air out of it. Tighten the nipple before releasing the lever or it will draw air back into the line. |
