That incident is indeed scary. You were fortunate enough to control the vehicle again. I had a little similar incident too, but in my story I was on a highway with my fully loaded Yaris at almost 80 kmh. I tried to overtake a truck, but then had to slow down and apply brakes as the overtake seemed impossible. As soon as I pressed the brake pedal, my Yaris suddenly swerved to left side and at this very moment the brake pedal was still pressed. The car control was almost lost and I did the same as you: removed my foot from the brake pedal and steered the car to the centre of the road. If it hadn't been my instincts, I would have been out of the road and down into the ditch. After the incident, I went to 2 different 3S dealers and complained about the brakes, but to this day it hasn't been resolved and remains a mystery. Maybe some senior Pakwheelers can guide us all. Lesson learned: can't trust my vehicle because of its abnormal behaviour, and now I drive slowly and very cautiously.
