My 97 F150 has new front pads, rotors, calipers, brake hoses, rear wheel cylinders, brake shoes and drums seemed to be in spec, master cylinder and power booster. I still have a low pedal. I bench bled the master cylinder, I've bled and bled the brakes. I still have low pedal, but the truck will stop. Any ideas?

Thanks

Check that you do not have excessive pedal free play and try gravity bleeding the brakes, attach a clear plastic hose to the bleeder and crack it open, allow fluid to flow for a min or so then hold the plastic tube up and watch and wait till all bubbles stop, if they do not stop I would suspect a faulty master cyl, the bubble should stop after 30 sec or so, try this first.
