Brake help for the 40
I'm about to get back on the 40 rebuild and I see it sitting in the garage with the fenders still off and that front axle leaking and needing some love. I was going to put it off but I'm thinking now might be a good time to get some disc brakes on the front of her.
I've seen and heard many different ways to accomplish this but need a little direction, advise and/or help to get it done.
I'd like to do this now as I'm also doing the saginaw conversion and want to do it right the first time!
Thanks for any help...

I went with the 60 series conversion. It is pretty straight forward and well documented conversion. The raw materials can be sourced from a solid axle mini truck, FJ60 or FJ62. You will need everything from the knuckles out and the steering arms. You will want to give strong consideration to replacing the bearings (wheel and trunions), new rotors, new calipers during the swap.

About the only thing easier is to get a disc brake front axle from a 40 and swap it right in.

You will really like the disc brakes. I ended up doing them in the rear as well. :D

We did this sane set up for a tech night. I even mixed and matched with 4 runner calipers supposedly more pressure and fj60 stuff. I also liked that I got aisin hubba with the set up.

This was a huge upgrade. Adding monte Carlo rear Discs allowed true brake power.

Ok so any idea where I could source the parts?

PM ArtVolmer - he has a 60 that is being parted out. :thumb:

There is an FJ40 disc brake setup on CL currently. It is from a mini truck. I do not see he locking hubs are there.
