As I was driving home, the check engine, the trac and vsc lights all came on at the same time. I also heard a hissing noise when I pressed down on the brakes. I went to a mechanic to see what the problem might be, but it was late in the day and everyone was closing. He told me it sounded like a vacuum leak in the brake booster and to bring it back first thing Monday (he seemed to think it'd be okay to drive over the weekend). On the drive home the brake light came on and there were a few times where I was afraid I wouldn't be able to stop the car at all. It was quite scary! I was pressing the brake pedal as hard as I could and then it finally grabbed, the car jerked, and the seat belts tightened up around me. I worked today (Saturday) and the same thing happened to and from work, only now I am using the emergency brake to slow the car and I put it in park at stop lights. My next trip will be straight to a mechanic! it seems it is not common for brake boosters to fail and I am learning that other Toyota Rav4 owners have had the same problem, several ending in accidents. This should definitely be addressed by Toyota, as it is a huge saftely issue, and possibly be cause for a recall.
