Driving down the road and I got a service trailer brake code pop up and would not go away and kept dinging it is very distracting and sometimes causes the trailer brakes to malfunction.
When braking, the service trailer brake system message and service stabilitrac message appear on the dash and brake pedal gets soft to hard repeatedly and truck pulls from side to side violently as if one side of the trucks brakes are working and the other side is not.
Brake pedal has to be pushed almost all the way to the floor to stop, this recently changed from barely having to apply any pressure to the pedal. Took it to quebadeaux GMC on 11-10-2021 and they inspected the brakes, said everything was good and that’s normal for the brakes to be that soft. That’s not normal or it would’ve always been like that.
The brake booster cilynder have a bad leaking it was parked when I saw this happen.
