I was having soft brake issuesl, seems common on these trucks. Turned out to be a leaking rear axel seal. Replaced the seal cleaned everything up adjusted the brakes and all is well.

Thank you Mr. Schurkey supporting member. For the record I took time to post this for other members benefit. Not to have you "Critique" it. I'm a mechanical engineer so yes if the booster fails and or the engine shuts down or the vacuum hose to the booster fails you will have increased pedal pusher. Wow I guess??? Thank you for your 2 cents.Of course you have "better" braking. You have much larger caliper pistons for more force on the pads and rotors. The new pads may be more-aggressive, too.
You may have replaced defective hoses, and/or a defective ABS unit. Either of those could reduce braking power if defective.
The downside is that the K3500 calipers would have been used with a 1.25" bore, two-chamber master cylinder, and you've got a ~1.5" bore two-chamber master. The pedal will be higher, but it'll take more effort to stop than the 1.25 bore it should have. This may not be important now, but if your booster fails, you'll need strong legs.
You missed the point.I'm a mechanical engineer so yes if the booster fails and or the engine shuts down or the vacuum hose to the booster fails you will have increased pedal pusher. Wow I guess??? Thank you for your 2 cents.
IF (big IF) the booster fails…

In general, they're both very reliable.Which systems are more reliable based on field experience, vacuum or hydroboost?
I do recognize that the failure scenarios are quite different, e.g., on account of the hydroboost’s dependence on the PS system.
Wild Guess with no evidence: I'd be most concerned about a PS failure that disabled the Hydroboost. And even then, the Hydroboost accumulator "should" give you a stop or two before the booster is useless.
-GMT400 dually front brakes can be swapped onto a SRW truck. The rotors are essentially the same size as gmt800 brake rotors (1.5” thick and a 12.87” diameter is available)
