Try adjusting your pedal
At the top of the clutch pedal in the cab of the truck.
Inside the truck behind or on the clutch pedal
Air in the clutch line and needs to be bled.
It should be mounted to the firewall on the other side of the clutch pedal.
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. This can be a bad master or slave cylinder, or a leaky line. Bleed the clutch, and then keep checking the fluid daily to see if you are losing it.
check your clutch slave cylinder for leaks,its bolted on your transmission,about 20 bucks
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.
Haydraulic brakes cant be adjust,check your clutch master cylinder for leaks,also look where it comes thru firewall to clutch pedal for leaks,check slave cylinder for leaks,its bolted onto transmission with clutch line connected to it,if any of these parts leak,replace,if no leak is found,then you will need new clutch kit installed.
Modern Class 8 trucks have no more pedals than a passenger car. If it's a manual shift truck, there's a clutch pedal, brake pedal, and accelerator pedal. If it's a fully automated, clutch free automatic, there's a brake and an accelerator pedal.
If you turn the ignition to the on position, and then press the interlock button, you don't have to press the clutch pedal down to start the truck.
