lol you guys.
well from my personal experience, the difference when working the truck was so drastic.
i can't argue or claim to know what may or not be better in any given situation but this is my first hand experience between the two:
chip truck started out with bad brakes.i bought it with very low miles.under 50k miles.the truck had been used for plowing.so with plowing and sitting the brake system had to all be replaced.when i say all,i mean all.you name it on the brake system and i replaced it.save for the ABS.that,i bypassed.everything else,new.
so i added some rear leafs and a dump bed and i could haul a nice load.i mean a couple ton with ease.the problem was the brakes just turned to mush when loaded up heavy and if i forgot about a road to take and didn't slow down for it,forget it.i just had to slow down and plan on turning around and going back.there was no quick stopping the truck.
then i almost hit a car in traffic.that was it.i had read about the hydro swap from Dave S on FTE (a mod there at the time,who was another heavy hauler with his truck) so i knew just what i had to do.so i ordered up the parts and did the swap.
once i swapped to hydroboost (i used the trucks master and the trucks pedal,not knowing better at the time) my truck all the sudden felt like it was made for hauling heavy.i could stop the truck in a very quick and safe manner with a full load on.in was such a drastic difference the whole truck felt totally transformed.i can't even begin to explain how much safer my truck became that day.now Dave S had shared his stories with the increased stopping power so i expected just what i got but i didn't really know it would be as a drastic difference as it was.im completely beyond impressed with the hydroboost brakes.
better or worse in some cases.might be.all i know is my truck is extremely more safe than it ever was with vacuum brakes.there is so much more stopping power with the truck now,that i honestly think comparing the system to vacuum is just insulting to the hydroboost lmao.seriously this is my story and im sticking to it.hopefully it helps someone else before they get into an accident too.
side note;
this thread is the first of its kind iv ever read.iv never seen claims of vac having any such upper hand over hydro before.im intrigued but i can tell you one things for sure.i wont be swapping to vacuum on the f250 or f450 anytime soon.
