Clamp all of your flex hoses off and try the pedal.. It should go solid. If it still allows for two pumps then the prob is in and around the master cyl or load bias valve.. If you have a solid pedal, remove one clamp at a time and gauge where most of the travel is.. Pays to have all the wheels off the ground too and make sure that all the adjusters are holding the shoes tight to the drums.. If one adjuster is not working, or a brake shoe is in backwards so that the pin is not working on the cam, then one shoe can cause two pumps! Good luck.
