my chevy s-10 blazer(4.3 ltr.) brakes just got real hard to push, with very
little power. I looked into replacing vacuum hose and check valve, but it
comes up as "not necessary" or N/A. Is it probably the booster???

Probably. All vacuum bossters have a hose and check valve, just because it
says N/A doesn't mean it's not there. Quick check: With the motor off,
pump the brakes a few times and then hold the pedal down nice and firm.
Start the truck with the pedal still held. It should move down towards the
floor a bit and soften up when the motor turns over. If it doesn't, likely
the booster.

Check the vacuum to the booster,if you have vacuum then replace
booster
