Very good summary. I'm not in the brake business so having all that info succinctly presented in a single post demonstrates the dynamics and complexities of braking systems, and offers up a lot of food for thought.
I've always been very conservative when it comes to a critical system like brakes. Never even attempted a pad/shoe change on any car until I was quite confident in my vehicle maintenance skills. Too much at stake for my liking. It speaks well of you gentlemen that I am comfortable enough in your expertise to consider modding my brakes based on your design work & research.
I offer my profound respect & thanks to all involved in this.
