If the pedal just randomly falls to the floor, you probably have a broken pedal or linkage. If we are talking about it having no resistance when you press it and the clutch not disengaging, you probably have a leak in your clutch hydraulics.

To adjust the clutch and linkage on a 1988 Ford F-350 Super Duty tow truck, first, locate the clutch linkage under the dash or near the clutch pedal. Adjust the linkage rod to achieve the proper clearance between the pedal and the clutch fork, ensuring a free play of about 1 to 1.5 inches at the pedal. If necessary, adjust the clutch cable tension to ensure it has the correct amount of slack. Finally, test the clutch operation to ensure smooth engagement and disengagement.
the slave on this truck has no bleeder, you simply need to pump the pedal about 500 times until you get some clutch movment. Then i recomend parking the truck on a steep grade and pump some more.

Tighten the bolts securely, and test the switch functionality to ensure it engages properly when the clutch is pressed.
