No Brakes!!
Heres the story....driving on Sat. everything OK, then the brake pedal got soft, then it went all the way to the floorboard, car barley stopped and the "Brake" light goes on when the pedal goes to the floor. No brake fluid leaking from anywhere....where do I start to get this problem fixed????
Simplest and cheapest, bleed the entire system. You'll be able to get a good close look at all of the calipers and as you go around one by one, if there's a leak, you'll find it fast.
First guess would be master cylinder. Usually when you get a soft pedal and no brakes we think M/C. Hard pedal we think brake booster.
With a new M/C you should be in good shape. Might be a good time to do a complete flush and bleed.

Put in the new master cylinder yesterday, installed speed bleeders and did a complete fluid change/bleed.....good as new. Thanks to everyone for their help!!
