I've adjusted the parking brake shoes per the manual, but I still go all the way to the floor on the parking pedal. The parking brake does engage enough to hold the vehicle. However, I'm used to having a little reserve in the parking brake pedal.

Is there anotheer adjustement that I am missing?

no, and you probably should not even done what you've done. parking brake is made that way. all the way to the floor, no resistance, and just enough to hold vehicle. my silverado is excatly the same way, and i have researched the issue for long time, until i got the same answer. i think they made it keeping in mind old debilitated ladies.
