Question about Nissan Pickup
You have air trapeed in the system. either do a gravity bleed at each cylinder or buy a cheap pressure bleeder at Harbor Freight. Usually air is trapped in the disc brake calipers.

Check for leaks at the slave cylinders and flexi hoses.
After several attempts of losing pressure - check the brake fluid level in the master.
If you arn't losing any fluid, You've got a damaged seal in the Master cylinder, or are drawing air in due to improper adjustment (excess travel) of slave cylinders.
Are you trying this with engine running? - How does this affect it (using servo assist)

SOURCE: '92 Jimmy rear brake failure
have you checked the vacuum source of the master cylinder?. if it has a leak then it wont work properly. check the hose from cracks and chippings. check where it is connected and check if you have a good source of vacuum from your engine
is the pedal hard to step unto?
you have replaced everything and that is the only part that you have not look unto yet.
i hope i was able to fix ur problem..

did you bench bleed master cyl. before you installed it? its either you did not get all the air out, or you got a defective master cyl. if you did everything right and it will not hold pressure, than i would say its defective. believe me you do get bad ones, expecialy if they are remans.

hi from the uk have had this problem on a customers car b4 who had replaced frot calipers and pads and pedal went to floor on inspection of caliper i found that the steel spring clip that fits into two holes in the front face of caliper and must also locate behind the caliper carrierbehind two lugs was fitted incorrectly it had been fitted behind the outer pad resulting in when brake pedal off ?the caliper being floating type as it is known because it is fixed by two screw pins/bolts and moves on these pins/bolts as pads wear ? what happens is the spring fitted wrongly ? actually pushes against the outer pad and as a result the caliper piston is pushed back into its cylinder slightly as it moves on the locating pins/bolts resulting in pedal going to floor on 1st application but if pumped ? some brake pedal force is felt but is lost again when pedal released ? so try this ? remove the steel clips from both front calipers that retain caliper to carriers then press brake/pump pedal ? if as suggested above works? your pedal should pump up and remain ok when you release and still be firm when re applied ? all above is what i found on ford ford but many other models use similar calipers and spring locating recheck how this spring should locate hope this helps ? good luck
