Here is a guide that will help get us started on this issue:

I suspect the issue is the hydro booster. I have seen this in the past and they more then likely have a leak allowing the pedal to drop at times. It could be the master but I suspect the booster is more likely to be the issue.

Below you will find the detail on how to replace this for your truck.

Let us know if you have other questions. Thanks
