I have a 91 Honda Accord Lx. My clutch pedal works fine when I push it hard and fast but falls to the floor when I push it slow. What would cause this? I have replaced both, master and slave cylinders.

Thank you for replying. Yes, we have bled the system and the clutch works great and I can drive it as long as I pump the clutch to shift. The problem is that the pedal falls to the floor if I press it slow.

It sounds like either you have air in the system or you have a bad clutch master cylinder.

That black stuff is old fluid that was never changed. All that has to go and new clean fluid needs to be in there to prevent further failures.
