Cascadia clutch brake adjustment?

At the bottom of the bell housing, there'll be... well, usually, there'll be an access cover, although some trucks don't have this. You should have 1/2" of space between the clutch brake and throwout bearing, and that should correspond to 1-1/2" of freeplay in the pedal. If you don't have someone to bump the engine for you so that you can get to the adjustment pin, a 3/8" or 1/2" drive ratchet with a 5/8" socket, and a small prybar (you have to push on the back of the ratchet in order to push the adjustment pin in), then it's a bit pointless. Plus you'll need whatever sockets for the bolts for the access cover.
In all honesty, it's really difficult for me to explain what you're looking at and what to do without giving some sort of visual reference... I can do it, I could show you how, but talk you through it? I'd be terrible at it.
There are other things which could be causing this, as well... your clutch brake could need replacement. I'm assuming you drive for a company? I'd call your dispatcher/DM/whatever you want to call them and request a PO to have this checked out at the nearest service center or company terminal (if your company yard has a shop). Not to mention entry level carriers typically don't want drivers working on trucks.

 

Witching hour is quite correct except one thing. It is not the 1/2" space between brake and brg that gives you 1" free travel. The 1" free travel is a result of having 1/8" gap between the release brg and the release fork fingers. But it is correct that a max of 1/2" is required between clutch break and release brg.

I would ask you if you still have clutch free play? As a rule when the clutch is set up properly clutch break gap should not need adjusting again (clutch break gap is set by adjusting linkage which is not a normalally performed adjustment) As the clutch is adjusted for free play the release brg moves back towards the trans. So adjusting increases the distance between release fork and brg (freeplay) aswell as decreases the distance be the brg and the clutch brake. So as I stated if the clutch was set up properly at the start a clutch adjustment will usually correct both free play and clutch brake.

 

All my Cascadia's since they came out are hydraulic clutch. Might check for leaks/air/loose mounting.

 

Does the Cascadia have a hydraulic clutch, too? I thought it was just the Volvos and Kenworth T680s which had them... IMO, a stupid feature for a truck, but whatever.
