FatTony - Congrats on your find! thumbs_up

Here's an old detailed and extensive thread from long time Stovebolter Grigg on Disc Brake conversion for Big Bolts front axles.

Unfortunately the picture links are long ago dead, but perhaps Grigg still has them stashed somewhere and can repost them???

Here's a newer thread on a similar thought process from TUTS 59 on his 1958 4400 front brakes.

Anyhow, these are great starting points for you to see whats been done in the past, for the front brakes. On the rear axle/brake question, I'm pretty sure someone has either considered or attempted this swap out, but at the moment I can't seem to find the links to any of those threads.

Others should be along soon to add more info and experiences. smile
