We just replaced both the Master and Slave Cylinders and now there is no pressure. We have sat there and tried to bleed the system but the fluid level doesn't change. Why won't it bleed to put the pressure back in the clutch?

 

Watch ETCG bleed a honda slave cylinder, bleeding process starts at 17:18


its important to use the hose and bottle to prevent air from returning thru the bleeder and so you can determine when all the air bubbles have passed out of the system.
