I beleive the first thing you should check is your wheel bearings. If the wheel bearings are loose they will push the caliper pistons back and when you first step on the pedal after driving for a while it takes more fluid to fill the pistons and the pedal goes way down.( JUST A THOUGHT )

Brakes are drum would this make a differants?

If pumping the pedal helps, speed racer has one idea of what to check alth I don't think the shoes can be pushed out by a wobbly wheel like disc brakes could. I could be wrong tho. Bleeding and making sure you have no leaks and master cylinder full is a good thing to check.

Can not find amy leaks,when the pedal gets soft pumping does not help. It only goes back to normal after it cools. The only thing I know to do is to replace master cylinder. Stll open to new ideals
