my son has a 93 del sol and the other day clutch pedal was clear down to the floor. we have since replaced both the the master and slave cylinders and rebled the lines but the clutch is still on the floor. what else can the problem be?
Did you bench bleed both of them. If you didnt, do it bc it might still have air in the master and slave. If you did try adjusting the line and see if there is any difference
How many times did you open the bleeder screw to get air out? It sounds like you still have air in the lines. Keep bleeding.
Bench bleeding makes it easier to get all the air out before installing it but it's not absolutely necessary. My friend installed a new MC on my car without bench bleeding it. We didn't spend much time bleeding either.
