i'm using the stock pads still. the rotors are stock too. still the original parts with now 40K miles on the car.

when the rotors were warped last time, it was really bad. i'd feel it any time i touched the brakes.
now, it feels like it's slowly getting worse with time. i now feel it mostly at high speeds when i hit the brakes, and when i hit the brakes hard. also, as i'm approaching a stop/red light, the last few feet of movement i feel a little "stop and go" feeling. when the warped part hits the pads it slows the car, and then it goes smooth again once it passes. almost bobbling the car very slightly from front to back.
