As I was driving north on the 101 in the Carpinteria area, I attempted to brake for a construction zone slowdown. I had about 100ft to brake and was going 50mph compared to the 25mph of the cars up ahead. When I pressed the brakes, they did not fully engage and rather appeared to 'slip'. It felt like the brakes were engaged but not limiting the slow of the car in a significant manner. I rear-ended the car in front of me causing that car to hit the car in front of it. I could smell a strong burnt smell during and after the event. The car and brake piece are still available for inspection for another week or so until insurance is done investigating the car for the report, at which point it will be signed over to the scrapyard where it is currently being held (Steelhead Auto Recycler). This incident absolutely endangered my own life and the lives of the individuals of multiple vehicles around me. If I were going 10mph more than I was at the time I wouldn't be typing this message right now. I had absolutely no control over the speed of the car, and because of the construction there was no way to avoid the car in front of me. The lives of the family in the car in front of me were also especially endangered. The specific piece is not being inspected by the manufacturer or the police, although it possibly could be investigated once insurance does follow up with the report. There were no warnings that this was going to occur. In fact the car had its brakes checked just 2 years prior to this incident and it completely passed inspection with no concerns. Brake failure is not an experience I would wish on anyone in the world. It is absolutely petrifying in the moment and can result in devastation of so many lives.

The owners and or sellers of this dangerous and life threatening vehicle that was sold to me knowing that the car was in extremely bad condition. These criminals sold me the vehicle knowing that it was not smog cleared or approved. They sold me a fatal accident waiting to O happen! they intentionally modified the odometer/mileage to 85K/95K... but when I ran a check on car fax, it clearly showed that this vehicle was 206,851 miles of wear and tear to engine. The break system almost killed me on the freeway and made me lose control and forcefully made me spin out of driving control for 3 full spins in the middle of the freeway, bu the grace of god, I missed all incoming traffic.

While approaching the gate to my office parking lot this morning, I attempted to come to a stop while the gate opened. As I approached the gate, I could have been travelling no faster than 4-5 miles per hour. The brakes failed to react. I floored the brakes, but to no avail, and crashed into the gate. Fearful of the safety of the car, I had it towed to the Nissan dealership, and I was informed that there have been past issues with the 2007 Nissan Altima master brake cylinder. After checking the car, I was informed that it was a problem with that part. It had leaked internally and at the time I attempted to brake there was simply no more fluid to provide pressure to the brakes. I asked if this could have happened at any speed, and was told that it could have done so. Apparently the NHTSA has dealt with complaints on this before, but as a second owner of the car, I had no idea this issue was out there. Had I had to brake at a high rate of speed, there could have been serious casualties or even fatalities. Please investigate and consider a recall of this car.

I started my car on the morning of 11/21/2012 and noticed my brake light (!) pop on, I looked in the manual and read my brake fluid may be low, I checked and it was low so I added some the light is still on, I have read many complaints that the master cylinder may be bad.

The brake feels like it is sticking. When you press the brake and release it, it feels like is it is not coming back all the way. Also, when you press the brake sometimes it stops or slows suddenly or fast, and other times it is normal.
