Front Disc Brakes

There are no brackets for the early spindles that I'm aware of, they are made for the larger '37-'48 bolt pattern.
 
As I am beginning to understand it I would first need to switch to the 37-48 spindles and then get a disc brake kit to go with them? Would i be able to maintain the 5 x 5 1/2 bolt pattern?
 
In my opinion a better solution would be to design and make brackets to fit the disk brakes to the Model A spindle. Not everyone can do this. The way to go about it is to buy the parts then design the brackets. It may take making a new disk or modifying the disks that are available, or maybe an adapter. Look at Wilwood racing calipers and disks. Someone did this for the Model T after a friend of his died because of failed brakes.

Start here: https://www.wilwood.com/BrakeKits/BrakeKitAdvisor?year=1930&make=Ford&model=Model+A&option=Base

The Model T brakes can be seen here: https://www.modeltford.com/item/2565.aspx That may be a good place to start.

Mike Hoskins makes a well-engineered set of disc brakes for Model A's, called Hoss Brakes. He has a set on his '31 coupe and has gone into production. He has his rotors cast and I can't tell you for sure how the rest is done, but they're ingenious. His phone number is 816 352 7097. Tell him Jim Speedster sent you.
 
After I got the spindles and hubs modified to later model I used a Wilwood kit that bolted on with no additional mods.

PS I can fit model a spindles but not sure of the offset or the shimming of it ,,,, the kit I have will work but I made it for 40 style spindles , my kit you can change it to fit about anything that has a 5 on 5 1/2 wheel pattern thanks mike
 
A friend put disc brakes on the front of his Model A. The brake dust ended up all over the wire wheels and he regretted doing it.

I've had a couple great conversations with Mike and seen some pictures. His set ups look and sound really good and I'll be seriously looking at it when he has the parts and the kits assembled.
