Question Need Help.... Braking is poor!

I've got an 84 3/4 4x4... Front disc.. rear drum. I've had the rotors turned, new pads, new driver side caliper (old one seized up) & brake hose (replaced this before the caliper) . Essentially, even if I slam on the brakes, it won't come to a rapid stop, nor even lock up the tires and skid. The pedal has decent feel... the fronts have been bled repeatedly. I can't bleed the rears as the bleed screws are stripped & will have to be drilled out (which I plan on doing fairly soon).

At any rate, tonight while coming up on an intersection, the light changed and I was probably 200ft back or so. Plenty of time to stop from 35mph - or so I thought. I put the pedal to the floor... the truck comes to a slow halt about 15ft out in the intersection. Not good. I've never had to use the brakes so hard before, so I'm not sure if it's always been this way or if it's a recent problem.

Does anyone have ideas as to what could cause this? A couple of buddies said a check-valve controlling vacuum to the brake booster could be bad? Or since I lifted the truck 4" the height-sensing proportional valve could be screwing up the front-to-rear braking bias? Or my new pads (WearEver - Advance AutoParts) could suck? Or...... ???? I'm looking for ideas... I don't have a lot of $$$ to chase this problem... so I'll go with what sounds most likely for starters!

Thanks a lot! I really appreciate any help you guys (and gals) may provide!
