That is the hub was used in the little five hundred and yes it did groan under hard braking conditions. I have had hundreds assembled and re-assembled in my life as a mechanic. It is a metal on metal brake system, and the steel can and will groan under hard braking conditions. As the hub and brake pads inside the hub age and harden they will make more noise,just due to the hardening. But they will always work even though noisy. I currently have three here in the shop to re-build and the all will need no new parts just a cleaning and rebuild. The design hasn't changed in 50 years and still works fine. HTH, MH
