Yes & no.
Yes, I used the Hydraboost equipped pedal w/the vacuum equipment swapped over. Yes, the truck stopped. But, I felt it could be better. I had a master cyl on there w/1.25" bore & felt a smaller 1 1/8" bore might help pedal pressure.
But.....I kept having issues w/master cylinders leaking from the main piston area (seeping out the back of the unit & down the boost canister). At first I thought it was the 'house brand' replacment master cylinders until I finally got a new Wagner unit & it eventually did the same thing.
Initially when I got all the requisite swap parts, many of the brake related parts were already pulled. Upon mock-up, I realized the booster did not have the dowel pin/rod that goes between the vacuum can & master cyl (it must have fallen out when relocating parts). I didn't know if the lengths of the dowels were the same or not between the vac set-up vs the HB. I took some measurements & opted to make my own dowel pin/rod based on other vac set-ups I had sitting around.
In the end, I now have the original HB dowel pin/rod in place. It hasn't leaked since swapping back, but I also haven't driven it since swapping the dowels (was waiting on my PB lower a-arms & Ride Tech sway bar). I did some testing w/it sitting in the shop but that's not 'real world' IMHO because of the trucks weight coming into play.
I have the front end re-assembled now but no seats in it so driving will still be a challenge
