Have you been bleeding with a vacuum bleeder tool or the conventional way. A vacuum bleeder gets out more air provided that everything else is done correctly.Like the correct wheel sequence depending on weather you have rear wheel anti-lock only or four wheel abs.Refer to a Haynes repair manual.
e-brake pedal should go farther- is either out of adjustment or cable frozen- secondly sounds like only front brakes receiving enough pressure to "activate" properly- bleed all four brakes starting rear pass,then rear drive ,then front pass, then front drive- use plenty of fluid- bleed till fluid is clean without bubbles- will that long at first- this will insure not bubbles and no moisture- if a pro valve dies,you would have more problems- pedal would be really soft,would have both a brake light and abs warning lights
It sounds like master cyl. is drawing in air causing prob. also another test would bee too bleed out and get pedal back, now step on pedal and hold firmly and see if pedal creeps near floor indicating innternal leaking in master cyl. also have some one pump bakes slowly aand look for air bubbles in brake res. after bleed out indicating master cyl. is drawing air upon release of pedal.

Check the brake hoses. The rubber hoses that come from the hard line, (Metal), to the caliper. If these are the original ones that came with the vehicle, they are overdue to be changed out.
Do they have any weather cracking on the outside? No? That's okay as they break down on the inside, and sometimes this isn't apparent from the outside.
The rubber brake line is a composite. A sheath on the inside, then a steel braided hose, then another sheath on the outside. The sheath on the inside breaks down, and a piece of the rubber compound blocks the hose opening, when you step on the brake pedal.
The brake line can also swell up a little, as you step on the brakes, causing that spongy feel.
DON'T KNOW IF U DID BUT U NEED TO BLEED THE BRAKES IN THIS ORDER RIGHT REAR,LEFT FRONT ,LEFT REAR AND RIGHT FRONT.IF THAT DOES NOT HELP SOMETIMES U CAN ADJUST THE ROD BETWEEN THE BRAKE MASTER & BOOSTER.U HAVE TO REMOVE THE MASTER TO DO THAT.U MAY HAVE A BAD MASTER.
