I agree it’s caused by a defective vacuum pump. But my original comment was based on not understanding exactly what you were saying. Sent from my iPhone using Tapatalk
No. It happens at or just above idle AFM has nothing to do with it. Windshield wipers stop working it’s that damn AFM lol. Sent from my iPhone using Tapatalk
When stopped with the engine idling and I pump the brake or even very low speeds I get the hard brake pedal. It’s like when you pump the brake with the engine off on other vehicles how after a couple pumps it gets hard. I never felt in danger though. Also never had any lights on the dash.

I have a Pioneer head unit with Maestro RR interface using factory back up camera and the picture is crap. Worse then the factory picture. Reason for this is the camera GM uses is crap.
Old truck with a rental trailer and new truck with new trailer. The new one still needs to be properly set up with weight distribution and stuff. That will happen next spring. Sent from my iPad using Tapatalk
