Style chooser

I'm driving the latest Myvi 1.3 and of late, I am experiencing some braking problem/discomfort. Whenever I apply steady pressure to the brakes, the car jerks back and forth (like a rocking chair) until the car stops. The movement is obvious when I brake during downhill and it usually happen from around 60kmh onwards to stop position. I tried looking for symptoms on the net and some said it is due warped brake rotors. But my brake pedal and steering are not vibrating at all. So... does this...
