I'd be inclined to think booster but if it has sat for along time it could be a lining prob. Might split the M/C from the booster & pull it forward several inches & start it & hit the brakes & report how it feels

Air makes a mushy pedal.Bad booster makes hard pedal.Check the valve in the booster.Just pull it off.If vacuum releases with engine off the booster is bad or the rods are not correct.The valves can get plugged also.Rocky

Shade tree test of power brakes:
1. With engine off, pump brakes 5-10 times to expend any stored vacuum in the booster.
2. Place foot on brake pedal with very slight, constant pressure.
3. Start the engine.
A power booster that is working will have the brake pedal drop under your slight, constant foot pressure once there's vacuum. A dead booster will leave the pedal where it is.
Note that a dead booster and one not getting any vacuum due to other failures (cracked/plugged vacuum hose, bad check valve) will manifest the same. You need to eliminate the vacuum supply issues before condemning the booster.
Down to just a blue car now.
