my brake pedal goes to the floor without much resistance, the car stops but not that good. I'm thinking it's the master cylinder, but would like another opinion.

thanks for the directions, but I this morning there was a fluid leak on the driveway so now i'm looking at the brake line itself.

brake line rotted out, this is unbelievable in a vehicle with only 82000 mi on it
