With the engine off, does the pedal pump up firm?
Give it a few minutes, is it still firm or does it require you to press it a few times?
If there are no visible brake fluid leaks, get someone to watch each of the brake hoses 1 at a time (the flexible black hose, 5 in total inc the rear body to diff) while you press the pedal, are any of them shot and expanding like a balloon?
Is it the firewall flexing 1"?
Are you using the cheap brake pads?
How do they test it over there?
Is it upto date using a calibrated machine that measures the vehicle speed, pressure applied to the pedal and deceleration of the vehicle?
Oh and you don't bleed brakes with the engine running, it's a simple hydraulic system, not trying to stop 2 tonnes with aid.
Not the case here, but if it's a 20 year old system, the last thing you want is the piston seals scraping through the buildup of crap in the bore and tearing the seals up. Only use half at most of the pedal travel to pump up and bleed (sit your other foot under the pedal so it can't go to the floor), you've probably seen the crap and buildup in a reservoir, now think about it sitting in the bore and a rubber seal running over it a few times where the piston seal normally doesn't go.
