Here is a tip that might help.
You might be able to rule out a bad master cylinder(or diagnose it) by observing the fluid level when the brakes are engage. The fluid level should drop slightly in the master cylinder when the brakes are applied (pedal held down). careful the fluid kind of jumps when the pedal is first pressed it can squirt at you with the top of the master.
The fluid level should stay down as long as the brakes are applied.
If the fluid returns to the same level (with the pedal still held down) then that could indicate a bad seal in the master cylinder.
The master cylinder is not that difficult to replace and the rebuilt master cylinders come with bleeding instructions and tubes. Part cost estimate under $50(?Auto zone).
After pumping the crud out of the brakes trying to bleed the lines it is not unusual that the master would go. Also if you are bleeding the individual brake lines start with the wheel the furthest from the master cylinder and go to the next furthest from the master cylinder. Rule out leaks before suspecting the Master cylinder. Sometimes the seal on the slaves will pop if rotor or drums are worn and pads a worn. This usually be seen dripping down the tire were the seal has popped (inside). when bleeding use a tube connected to the bleeder submersed in brake fluid so it doesn't suck air back into the bleeder while you are tightening the bleeder.

If you have bled them, then you may have to mess with the slack adjuster behind the master cylinder. What kind of work did you do to this car? Is there a leak somewhere in the brake system? Do you have a problem with your vaccum booster? Very little info to go on here. Good luck, though.

bleeding brakes is very simple. You may need to jack up the car. Follow the brake line into the wheel area, then find a little bolt thing on that where it attaches. Then loosen it. Wait until brake fluid comes out, then tighten.
It it makes the noise you say, I think it is still leaking. You need to replace that line.

You need to have them bled...someone needs to push them down while someone opens the bleeder at the brake to release the air....best if you have two people....good luck.

Can you elaborate on the problem? There doesn't seem to be enough information to determine what is going on and when exactly it is happening.

take it to a mechanic to fix the problem unless you are absolutely sure to can bleed the blakes properly yourself.
Your life is more important that the cost involved..........
