thanks for the replies. I have someone coming to look at it this morning before work. Here is what I think is happening.

Initially the internal star pin you rotate to extend the top of the shoes out was almost all the way in so when pulling the cable only the lower part of the shoes would have been grabbing = good leverage in the cab but no friction to stop or hold truck on a slope.

I removed the rotors and scuffed up the pads and the hub face as both were brand new.

I adjusted the star pin so that the disc wouldnt go over the pads, backed it off a couple of turns so i could slide the disc over the pads, then adjusted the join between the front cable and the nova cross over to take the slack.

What I think is happening now is that I have gone to far to the other way so that only the top of the pad is grabbing. = no leverage in the cab and no friction to stop or hold the truck on a slope.

I think I need to slacken the star pin off some more so that all of the pad face grabs the disc when applied.



anyone have pics of the factory setup i can reference. I know it ran a rod to a pivot on the chassis rail, then a cable through the pully to the middle of the truck but most if not all of everything from there out was missing or modified when I got my rig.

Cheers
