Too much brake pedal travel on mine was because the brakes needed adjustment. Press the brake pedal gently and slowly when bleeding them, and check that you can get fluid flowing well out of all 4 brakes. Top of your brake fluid. Then when you're all done with that bleeding turn the star wheel adjuster until you can't turn the drum any more by hand on both back brakes. Press and release the brake pedal again, then go adjust the star wheel adjuster again until you can't turn the drum any more by hand. When the star wheel adjusters are fully tight, then you can back them off a little until you can turn the drum by hand. Then see how your pedal travel is.
