pedal is soft at the bottom

1..How are the calipers oriented (front? rear? of spindle) and are the bleeders at the very top?

2...You can get let down "the path" by rear brake problems, such as oversize drums. Adjust the rear brakes out really tight, so the rear wheels don't turn. TIGHT.

Re--bleed the brakes carefully. With no power booster, you should have a "rock hard" pedal. With the rear shoes adjusted tight, you should have very little stroke to "hit bottom" perhaps less than 1/4--1/3 of the pedal stroke OR LESS.

New hoses? Factory hoses? Or are they an aftermarket fancy stainless deal?
