I had the same problem this weekend, took it to the dealer to inspect the brake system. We almost had a accident on the interstate, took a lot of work to come to a stop. (my thoughts, $80K truck should not have to pump your brakes to stop this vehicle)....

Love my 2021 2500 HD however, driving through the streets of Pittsburgh feels like I am bouncing all over the place.
my previous 1500 rode a lot smoother over bumps, is this common for the 2500 HD
