I was driving the other day and pressure to the clutch slowly was going away so i looked under the car and saw the slave leaking so i replaced that then when i put that on i didnt have any pressure at all and i kept getting air so i replaced the master cylinder while i was at it. I bench bled it but im still getting air and no pressure at all the pedal just sticks to the floor or sticks out no in between. I just bleed it regularly, didn't use a vaccum or anything. Any advice would be great thanks.

these things can be a real pita to bleed, you gotta have a helper and they gotta pump the hell out of it

Where are you bleeding it from? There are two spots, the slave then near the ps res. Bleed the slave then near the power steering res. Do it two to three times, it takes a few times to get all of the bubbles and air out.

I've bled it from both but no air bubbles ever come out the one up top but I get air bubbles and fluid everytime from the slave cylinder. Im gonna bench bleed the master cylinder again. Do you think i should bench bleed the slave cylinder too? And will gravity bleeding work on our cars?
