Default 1992 Bonneville Se Brakes

My 92 has been sitting in my driveway for about a month without being driven, when I drove it yesterday my brakes were almost non-exsistent. I have never had any indication of them going bad previously and it seems like I only have either front or rear brakes, it'* hard to tell but the car is very hard to stop.
Any ideas what it could be? There is brake fluid in the master cylinder and no sign of any fliud leaks.....I'm stumped and just wondering before I have someone look at it.
Any help would be appreciated, since I never had a problem like this with any other vehicle before.
Andrew

Have you schecked tha vac lines running from your upper intake manifold to the master cylinder? They might be corroded.

Default SE Brake issue

OK finally stopped raining here in PA, the vaccuum hose to the manifold isn't the problem, it actually looks fairly new.
Does anyone have any other thoutghs.....suggestions as to why my brakes suddenly do not work?

Could you be a little more specific about what happens when you depress the brake pedal? Does it go all the way to the floor? Or almost all the way to the floor?

If you monitor the master cylinder reservoir and observe the fluid level dropping within a short time, then you have a fluid leak somewhere in the system like a leaking hose, rusted line, bad caliper or wheel cylinder. A bad leak will cause the fluid level to noticeably drop within a few brake applications. But if you have a bad leak, you should find fluid on the ground or on the inside of your tires.

If you have checked the brake lines and find no evidence of any leaks, you most likely will need to replace the master cylinder. About $50 for a remanufactured part. You need to make sure you follow the instructions for bench bleeding the replacement unit before it is installed in the car.

Air trapped in the brake lines is compressible and can cause a spongy or low brake pedal. Usually air gets into the system when fluid escapes. You normally need to bleed your brakes after you open the system to replace a component (like the master cylinder.)

have the Rear wheel Cylinders ever been checked? They are a chronic problem among the H bodies and have a tendency to leak

If the car has been sitting, how rusty are your rotors?

If you know the master cylinder is good and has been bled properly, and you know that you have no leaks, then the cause of the soft or low pedal is air in the lines. Bleed the brakes at all four wheels to remove any air. If the pedal is still low, the problem may be that the master cylinder was not bench bled properly.
