if they only replaced your pads and drums, they shouldn't have had any lines open to ingest air. if they replaced wheel cylinders or calipers, it could need to be bled. you need to take it back asap. it could be that the rear adjusters are not installed correctly- those cars had a weird adjuster setup. you could have a rear wheel cylinder that is leaking after replacement of the shoes, or a wheel cylinder piston that fell out when reassembled.

Sounds like the master cylinder to me too! Here's how I usually find out. Hit the break pedal hard with the engine running. Then back almost off of the pedal a little at a time and apply pressure a little bit. Keep doing this and some times if the master cylinder is bleeding back, it may show up. As a rule of thumb, If you are loosing brake pedal pressure, but no fluid, the master cylinder's cups aren't holding fluid and it's going back behind them and back into the reservoir.

The most likely cause is air in the brake lines. Try pumping the pedal a few times - if it firms up, the air is coming out and you can continue until its back to a normal feeling pedal. If the brake light on the dash is on, you will probably have to bleed the lines. Get help if this is something you haven't done before.

Who replaced the pads and drums?
Perhaps the brake lines were not properly bled of air after the repairs. Air compresses and that can cause the pedal to go all the way to the floor. Brake fluid is designed not to compress, so that, if properly adjusted, the pedal will activate the system much sooner, leaving plenty of "push" in case you need to brake even harder.

Air in lines or bad master cylinder.
A bad power brake booster would make the brake pedal very HARD, not cause it to drop to the floor.

You have definitely have air in your line or your master cylinder is done.
Try jacking up your vehicle and pop the brake lines to your calipers. Once you pop the lines have your friend or family member pump the brakes 2 or 3 times to pump any air pockets or bad brake fluid. Repeat on all your wheels. This should clear up your issue. If this does not solve the issue then it would be more than likely your master cylinder is toast.

you either have a bad master cylinder or a lot of air in the lines on it still yet,try bleeding them out,if they wont bleed out you may have to replace the master cylinder on it,be careful it has anti lock brakes and refer to the manual for the procedure for bleeding these,good luck with it.

It could be your master cylinder is bad or your booster could also be bad.There is no reason you could have air in your system unless somebody had just replaced a brake line or caliper.Hope this helps.GOOD LUCK!

I would suggest bleeding the master cylinder then each wheel. Keep your eye on the fluid level when bleeding, if you run it dry your back to square 1
