Replaced slave cylinder on 1991 Isuzu pickup bled it and still clutch stays on floor now what next?

Answer 1

Try a clutch master cylinder. You have air in the system and unfortunately the pump has trouble priming. I worked at this for a couple of hours bleeding and bleeding and still no pressure, Talked to several factory techs and they knew less than me so this is what I did. I took some fuel line and a 12 volt fuel pump that I had laying around and put the suction end in a quart of brake fluid and ran the pump till the tubing was full, then I loosened the bleeder screw on the slave cylinder and pushed the tubing over it. I loosened the line going to the slave cylinder on the master cylinder and ran the pump until all the air was pushed out and tightened the connection and waited to see fluid rising in the reservoir, then I closed the bleeder and shut off the pump. Since my helper left me hours ago I pumped the clutch till I had some pressure and used a short pry bar against the clutch pedal and slid the seat forward till there was good pressure on the pedal then went around and opened the bleeder slightly just letting a little bit out and repeated this several times till I had decent pressure. The techs told me that the air bubble would eventually rise up the lines and exit at the master cylinder but I did not have any time to waste and this was my solution. Pretty shade tree I know but you gotta do what gets the job done when you have to be somewhere.
