i noticed that when i apply the brakes, sometimes it feels like the rear-end of the truck is jumping up & down, take your foot off the brakes & it stops. is this the "famous warped rotor" incident????? this is my first dodge dakota, drove broncos before this, & when they warped you knew it. the frontend would shimmy all over the road. so im not sure if it is the rotors, why would it feel like it was in the rear end???? my wife says she can feel a slight hopping just driving, but i don't feel that. thanks for the feedback.
