One of the scariest driving experiences I had was on the way to the Tappan Zee and while in the left lane someone broke hard in front of me, I hit my brakes and saw all my brake fluid squirt out from under my left fender and pedal went to the floor with no brakes.
No shoulder to my left when I hit the brakes and a split second later the road opened up with a shoulder and I barely got into it missing the car in front of me.
Got a tow home. Replaced that section of hard line, bled the brakes, drove it around the block and it stopped fine. Subsequently just said F it and parted the car out as that new brake line was the only non rusting part of the car. In fact my e-brake was all rusted and non functioning which didn't help the above situation.
