This Lexus RX330 was sent down the wrong path with a brake booster recommendation, but the real problem was low engine vacuum, not a failed booster.
The biggest lesson here is simple: test drive the car. A proper road test tells you whether the symptom matches the part being recommended. If someone had driven this vehicle and paid attention to the full drivability problem, they would have known this was more than just a hard brake pedal.
