The statements provided contain misconceptions about feedback mechanisms. Positive feedback mechanisms amplify changes or signals, while negative feedback mechanisms reduce them, aiming to maintain homeostasis. The classification into positive or negative does not depend on the effect being "good" or "bad," nor do these mechanisms inherently switch from positive to negative in stressful situations. Additionally, negative feedback is more common for hormone regulation, not positive feedback, and these mechanisms do not inherently contain or require "brakes" in the simplistic sense described.
