I pulled the floor mat today to check the brake fluid level and it was still full from when I topped it off about 9 months ago. Problem has yet to come back. Will order a new master cylinder this week as I don't want to wait for it to go out completely, it looks to be an original piece, not going to try to rebuild it, as replacement cost is only 95.00 plus shipping. Already have bleeder valves on the wheel cylinders. Truck was converted to 5 lug, thanks for all of your replies.
