I got into my truck Friday evening and it went to the floor. I’ve changed the master cylinder the line and the slave cylinder even put out the extra cash for the original fit clutch line. I’m getting fluid from the master all the way to the slave tighten the bleeder screw my wife pushes the pedal down and it goes to the floor and the push rod doesn’t engage the forks at all.

Vehicle Transmission and Drivetrain Clutch Service and Repair Procedures System Bleeding
SYSTEM BLEEDING
Note: When refilling or bleeding system, use on new brake fluid conforming to DOT 3 or DOT 4 specifications.

1. Raise and support vehicle.

2. Remove slave cylinder retaining nuts, then the slave cylinder.

3. While holding Slave cylinder at approximately 45 degrees with bleeder at highest point, have an assistant depress clutch pedal while opening bleeder valve.

4. With clutch pedal held at end of stroke, close bleeder valve and release clutch pedal.

5. Repeat steps 3 and 4 until all air has been expelled from system. While bleeding clutch system, constantly check master cylinder reservoir fluid level and replenish as necessary to prevent master cylinder running out of fluid.

I’ll try that for sure but my truck everyone says my clutch is inverted meaning I have to raise the clutch pedal up and leave it up when you depress my pedal it stops all flow of the fluid to the master

Welcome back:

I just checked pro-demand (Snap-on) and Alldata manuals and both indicate the same bleeding procedure I indicated. I'm not sure if you have something different, but that's what is indicated. Try it and let me know if it works. If it doesn't we'll figure it out another way.

Take care,
Joe

Is it supposed to take like a few minutes before the clutch comes all the way back up? Jus wondering if that’s normal or if my master cylinder is busted
