If the vehicle is equipped with RWAL (Rear Wheel Anti-Lock Brakes) which were standard equipment (4 heel anti-lock was optional), it's quite possible that the combination valve is defective. Over time, these valves get full of rust and can stick in any of 3 positions, open, closed or in between. To rule out the master cylinder. remove the two lines at the cylinder and put bleeder hoses in the ports (very cheap at an auto parts store). If it holds good pressure, then most likely the combination valve is defective. Unfortunately, there is no mechanical test for this valve, and it's a couple hundred dollar "shot in the dark". The problem could very well be the Master Cylinder, I just wanted you to know there may be another possibility.

There is air in the brake lines. Re-bleed the brakes, starting with the farthest from the master cylinder. If they still wont hold after they are bled, you will probably have to replace the master cylinder.

Have you tried your master cylinder? There is a pressure valve in the cylinder that when it goes bad fluid will leak past that. Make sure you don't run out of fluid in your MC when you are bleeding or you will have to re-bleed everything.

Sounds like the primary in the master cylinder is bad. If you have no other external leaks this will be your problem. Replacing the master cylinder should resolve your problem.

you nevertheless have air interior the strains. Air oftentimes gets in whilst the guy on the pedal helps it to return up beforehand the guy working the bleeder valve closes it. the guy interior the automobile would desire to shop the pedal on the floor till the bleeder valve is closed. you are going to would desire to bleed all 4 wheels commencing with the only closest to the grasp cylinder. you will desire to artwork out a equipment of verbal replace to establish that may no longer taking place.

sounds like the master cylinder is giving way.
does this have ABS? If so, you might have air in the ABS system, and that is impossible to remove without the scantool to cycle the ABS valves.
