General Motors Recalls 3.7 Million Vehicles Over Braking Issue | GM Authority
What did they do exactly? They talk about engine driven vacuum pump which the Dmax does not have, it uses hydraulic boost from the power steering pump.They just performed this on my truck yesterday. I did notice a "bump" coming to a stop like some people was talking about. But then I also went into Regen on my way home.

Just a programming change.What did they do exactly? They talk about engine driven vacuum pump which the Dmax does not have, it uses hydraulic boost from the power steering pump.
As for the bump you feel, my guess would be fuel sloshing in your fuel tank. Typically starts around 3/4 of a tank...
Same thing I thought. It is more than likely fuel. You should be able to duplicate the feeling in a flat driveway. Just have truck on drive at a stop inch forward slowly and stop. You should feel the bump almost everytime. You can also feel the fuel slosh if you have someone do this for you with your hand through the rear fender well on the rear of the tank. You can feel the slap of fuel on the tank.Just a programming change.
That was no fuel slosh. It was like the torque converter released late.

Thanks I didn't notice that at first. You are correct.What did they do exactly? They talk about engine driven vacuum pump which the Dmax does not have, it uses hydraulic boost from the power steering pump.
