They don't squeal on my 411.
Unless you have kevlar brake pads on your 411, I suspect the "Squeal Deterrent Kit" is missing.
The Girling front calipers used by Bristol included a "Squeal Deterrent Kit" which consisted of a thin metal backing plate behind each brake pad, which were coated with a special grease supplied by Girling. I have read that it is called PBC (Poly-Butyl-Cuppysil), but I suspect there numerous brands of anti squeal grease on the market nowadays - it has to remain thick and sticky at high temperature.
Edit/PS: I should add that I mention kevlar pads only because I experienced terrible brake squeal with kevlar pads on 2 Astons, but that doesn't mean all kevlar pads squeal. They did improve braking performance, but the noise wasn't worth it!
