I mean, it was fine one minute and then the next the brake pedal was going to the floor ...under just normal pressure? Happened to me backing out of the driveway back on Mother's Day in 15. I drove the car home from work on Thursday and it sat for like 3 days, then backing out of the driveway the brakes went to the floor. I could understand if someone slashed a hose ..... but just dying like that from natural causes is pretty freaky. It could be rather hazardous in traffic.
