I replaced both master and slave clutch hydraulic cylinders on a 92 Toyota Previa. I bled the air out but no pressure and no leaks. What gives?

I recommend checking for proper fluid level, removing the clutch slave cylinder and work the push rod in and out several times until the push rod can be felt to move fluid. What this process will do is to push air back up the hydraulic line and when the internal spring in the slave pushes the piston back out, the fluid will displace the air. I do this whenever I replace clutch hydraulics, it might not get every air bubble out, but it will allow the system to begin to operate normally and when the clutch pedal begins to firm up, the system will purge itself of the last bubbles. Does this seem reasonable to you mate?
