Hey Mr. Texas,
Very well thought out and explained in accurate, practical application terms , IMO!
I will add that I just put an entire Lincoln hydraulic brake system on my '30 roadster.
I debated long and hard whether to do this, as the mechanical system on my A was totally restored with added upgrade of cast drums. All restored or better parts ! Second reason for procrastination was the PRICE ! In the end, I sold my entire mecanicals system to a 'restorer' who was excited to see/get quality system for his project, and I got $ for my project ...quid pro quo

!
All the talk here about hacking/chopping up brake pedals, battery box , etc, etc...well I had NONE of that. Installation was straight forward and end result is a clean looking/operating system. I asked a lot of questions , prior to making the decision and preforming this installation. Mostly questioned the USE of SYNTHETIC BRAKE FLUID ! Man, did I run the 'gauntlet' of yes/no ! Now, my experience tells me that MOST replies on any subject come from guys who have never been there and/or done that

! Just parroting what indoctrination that they have encountered on a subject and not qualifying it as such heresy..bummer as this gossip throws a wrench into all, IMO.
Anyway, I opted to use synthetic brake fluid and am happy about that decision...for practical reasons, mostly that that fluid does NOT attract and/or absorb water as 'regular' brake fluid does , especially if it sets in an unused brake system. The water retaining property, which causes rusted and stuck cylinder parts...is the ONLY factual/real gripe that is spot on regarding the use of hydraulic brakes , IMO. Now since this is not the case with synthetic fluid use, I have no qualms with hydraulic system otherwise. Yeah, my A sits unused for long periods of time...as life gets in the way. However, I expect no rusty mess when I do eventually reuse my car.
I've driven for over 50 years and THE one thing that matters to me, is how well does this vehicle stop. Think safety here. You can get a car with a dead engine going down hill , very fast ! But, how well does it stop ? Now throw in an emergency/panic stop....and how well do brakes perform. If you do not consider these things (ostrich syndrome ) , make sure that your car / life insurance is updated when driving a vehicle. Now, the trend is to go faster, if for no other reason, than to keep up with legal limits and to keep from getting run over by 'modern' drivers/vehicles. So, you've hopped up that A with hidden upgrades to make it go real fast

! How have you compensated for making your brakes to slow the A real fast ?
I've tested out both my braking systems , on the same A. Tried to simulate panic situation and stop. Of course you have an advantage here that you will NOT have in most real life emergency panic stops. How many of you have done this with your driver ...with either system ?
This long winded thread and the many other long winded threads on same subject, IMO, will not sway many one way or other. Yup, 'it was an accident' , not my brakes that got me into this wreck. Safety is paramount and each driver has to contend with results of actions and/or non actions.
Mr. Texas would you happen to have any help/instructions on how you accomplished your disc brake installation on an A
