2007 Freightliner century with Eaton fuller clutch problems

Typically I would say your clutch brake needs an adjustment which is easy but you are saying that your clutch pedal went hard. The first thing you will want to do is remove the clutch inspection plate. Have some one work the clutch back and forth while you see what’s going on in there and see if something looks a miss while they are working the clutch

 

What cam said. Also check linkage and freeplay. Did freeplay change right when this occured?

 

Starting to think bushing came apart on clutch linkage from pedal to the trans. Not allowing pedal to be depressed all the way to engage the clutch brake. Would also explain pedal getting hard

 

How many little pieces of metal fell out when you removed the inspection plate?

 

iv had the same thing happen basically a spring broke and wedged itself in the clutch.

 

You will want to be watching this "mechanic" closely, some are not very good at the job and just start throwing parts at something since that dang computer told em to.
