If the brakes are stuck could that make it stall?

My shifter has h-d-n-r

Yes, I expected it to crawl when i shifted into 1st direct

My shift sequence according to the sticker is

1D 1H 2D 2H etc...

So it shouldn't be stolen when I shift into first?

Regardless of whether I give it gas or not

Hi guys,

New here. I just bought an 87 Mack R688st. First, I wanted to say thanks because I was able to fix a bunch of things on the truck just off of the information I found on this forum, so it's been invaluable.

Anyway, I have a 12 speed e6 350. (I'm a new driver)

Having a bit of an issue with the truck stalling, wondering if I should be doing something different.

I turn the truck on. Build up air. Push in the brakes. Push in the clutch shift the truck to 1st direct and then the truck stalls.

My question is:

Should I be revving the truck as I'm letting off the clutch to get into 1st gear?

Do I need to rev up a certain rpm?

I.e. shift into 1st at 1200 rpm?

Thanks guys
