Open the full vehicle complaint log (all categories)While driving my vehicle at 55mph on a country road, I went to brake, and then realized that I had no brakes. I had to coast to a near stop and put everything I had into pushing the little bit of brake pedal clearance left to the floor to come to a complete stop. I had NO warning signs or dash lights before this happened. Once I turned my car off and then back on, the service brake assist light came on, followed by the engine light. Had any cars been in front of me to stop, I surely would not have been able to stop with what little brakes I had left. My brake assist vacuum pump was removed, and inside there were many pieces of the part in there. This part is available for inspection. Again, had this happened in traffic or with anybody stopped in front of me, this would have had a completely different outcome. I had to have my vehicle towed 70 miles for repair. When the part was removed, there were no visible signs of any of the seals leaking.
