Pedal Pulsation
WARNING: This page is about a different car, the 2016 Dodge Durango. 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. Other causes are loose wheel bearings or calipers and worn, damaged tires.
NOTE:
Some pedal pulsation may be felt during ABS activation.
