lot of air in brakes

88 dodge dakota has "combination valve" and "height sensing valve" pedal to floor. replaced the master cylinder w/o improvement. When I went to bleed the left rear, coninuous small air, when I bled the height sensing valve, a lot of continuous air, and also the front right same prob. This thing is gulping air somwhere without obvious external leaks. I bench bled the master cylinder and it seemed OK. The other odd thing is the rear compartment of the master cylinder doesn't go down, only the front one no matter what I bled. Any ideas?

does your truck have a brake booster?
was it a new master?
waht does the pedal do?
does it stay firm for a bit and then goes to floor?

Have you tried to gravity bleed them?Open all your wheel cynlinders and let them set for awhile ,all the air should come out.When the fluid starts draining on its in close the valve
