Pedal Pulsation
WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
Pedal pulsation is caused by components that are loose, or beyond tolerance limits.
The primary cause of pulsation are disc brake rotors with excessive lateral runout or thickness variation, or out of round brake drums. Other causes are loose wheel bearings or calipers and worn, damaged tires.
NOTE:
Some pedal pulsation may be felt during ABS activation.
