Brake Booster Pushrod - Adjustable? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm putting a new booster in my 78 c10 (JB5) and I saw a bunch of videos talking about adjusting the booster pushrod so there is no preload on the MC, but when I'm looking at the new booster (a TuffStuff 2232NB), I don't see any provision for that (like there are no threads or anything to adjust).

What I DID notice is that the pushrod has some o-rings on it that seem to give it some pneumatic cushion when you slide it in. Does the booster auto adjust or something using vacuum?
