upgrade to 1932 brakes?

[Vanspeed]

A few people have told me I should update my front brakes to 1932. My car has a flathead 8 in her and I still run the stock A mechanical brakes. I bought some '32 spindles to get my tie rod more to my liking and this is when the conversation came up. "Why don't you swap to '32 brakes as well" I was not aware that there is a difference between A and '32 brakes. If there is what is it??
