NHTSA recall 20V-332
Those of you with 2015/16 trucks may want to be aware of this. My trucks braking has degraded to the point where I was about to order new brake parts. Looks like it will be making a trip to the dealer. I guess I might as well get a brake job done while they’re doing that.

Turbo charged engines have vacuum, There is only positive manifold pressure when the engine is accelerating, when the engine is in a decreasing rpm mode it has manifold vacuum just like a non turbocharged engine. So when applying the breaks the engine rpm is decreasing producing manifold vacuum
They use a 1 way valve to prevent boost from entering the brake booster system, it only allows flow in one direction...vacuum

I am not saying they have a vacuum booster tied to the manifold, all I said was that even turbo charged engines produce vacuum and those that do and have have a 1 way valve if they are using a manifold vacuum brake booster

Call the dealer service dept and ask them to check by your VIN. I got the letter based on my VIN. It’ll probably take a week or two for all of the letters to be delivered.
