Question about 2000 Buick Century
Seems like a vacuum leak. Either the valve, hose to the manifold or the booster itself is leaking air.

There could be 2 reasons that the pedal would go to the floor.1 -there is air in the system.If no one has taken a line loose then it will be #2 -the brake master cylinder has gone bad and will need to be replaced.Ther will be directions on how to do this proporely with the replacement unit.if you need further assistance let me know.

you have two problems here, your master cylinder has a leaking seal, the low pedal is resault, the power brake booster rubber diaphram is damaged and leaking from the brake fluid that is getting into it from the master cylinder, these are sold as a unit that has been rebuilt.

Testimonial: "Thank You for your response. However there is a new twist that I posted."
have you bled the brakes? If you have, you may need to do it again as there sounds like there's an air lock in your lines.

nope you have to replace them.when brake booster diaphram leaks you cant plug them.i have bought one at salvage yard in good shape.until i got a new one.get your brake booster from inside salvage yard where they stock them inside out the weather.dont take any brake booster off old outside cars been in all kinds bad weather. there vacuum diaphram probably dried up will leak also.

Check the floor for brake fluid.
The caliper / wheel cylinder and/or brake hose is leaking.
==== Master cylinder and reserve tank can also leak. Just look for brake fluid spot,
Replace the damaged part and bleed the brake.
