I doubt you have a braking system in that motor! However, the centrifugal switch sometimes gets mistaken for one because that is exactly the kind of sound it makes. Hard to explain with words, but the switch will snap back into it’s closed position sometime after you turn the machine off.. the motor needs to drop below a certain RPM for the springs to overcome the centrifugal force. 5-10 seconds sounds like that is what it is. I have seen it where they make very little or no noise when brand new and then start to become more pronounced after some use and increased clearances from wear. But heck, if they are willing to send you a new motor, I’d go for it!
