Did a few burnouts and next day pedal stuck to floor. I installed a new master and did the drill mod. I used a pressure bleeder and have good flow out of bleeder screw and when I pump pedal there is an incease in flow but with the bleeder screw closed the pedal m/c won't build pressure. I tried for 45 min then switched to 2 man bleeding for 30 min no help clutch pedal still limp. Do you have to bench bleed m/c I didnt could air be trapped because of angle of m/c. Bad slave? No leaks no clutch problems before burnouts. Suggestions please going back at it again tomorrow
