Driving 45 mph hit brakes and could not stop. Brake failure light appeared on dashboard. Kept pumping brakes and put into first gear to slow down. Luckily was able to stop and no one was in front of my car. . Inspected car and rear brake line hose was blown and leaking hyd fluid.
Was parked on a hill, when pulling away the brake pedal went to the floor but provided almost no breaking power. A few moments later, multiple beeps occurred with messages appearing on dash display (after the failure), about brake system needs checked or serviced, and stability system disabled. To catch the leaking fluid, I placed the pan under the driver's seat area. Lines looked totally rusted.
The brake light came on in my car and when I took it in to the mechanic, I was told the brake lines were corroded. Brake fluid was leaking through the lines and if I had driven for even another hour, I would have had no brakes. I had the lines replaced, which had to be custom built. The repair cost me $1188.
Lost all brakes when coming to a stop sign, rolled out into intersection, on inspection brake fluid was leaking out from under drivers side floor area. All brake fluid leaked out from reservoir.
Hard brake lines on frame under drivers door rusted through causing brake failure. While driving stepped on brakes and brake pedal went all the way down to the floor and vehicle would not stop. Noticed brake fluid leaking from under drivers door and saw that the hard brake lines on the frame were rusted threw. I had lots of older vehicles and never had the hard brake lines rusted threw especially in a 9 year old vehicle. Could have been very serious accident if it had happened on a highway.
Went to drive the vehicle, and noticed the brake pedal had no pressure whatsoever. Slowly drove the vehicle home with minimal brakes. Once the vehicle was parked, brake fluid poured from mid-frame driver's side. Considered vehicle to be unsafe until brake lines can be replaced.
Backing up applied brakes, pedal went to floor, stopped looked under vehicle seen brake fluid leaking from brake lines. Towed vehicle home, looking under vehicle fuel lines and brake lines are very rusted for vehicle with only 80,000 miles.

As I was driving home from work late this afternoon on July 05, 2011 on rt 589 in pasco county FL, I was coming off the exit to a red light and I could not stop. I had to push the brake pedal to the floor and hold it there in order to stop just short of the intersection. Luckily there were no cars in the right lane going through the intersection at the same time. I pulled over after the light turned green and noticed fluid squirting out above the passenger rear tire area. After I made it home I pulled the tire off and looked around and notice two heavily corroded lines where the fluid was coming out.
