It has been brought up time and time again about doing disk breaks on these 60-66 chevy trucks. So I am going to post this as a sticky in hopes that it will help everyone wanting to do the change. This will be a quick run down list. Ask questions for details.
as time allows I will sit down and edit this post and and a little more detail and then move it to the FAQ section. This thread then will have a redrect to the FAQ.
First you do not have to change the whole crossmember!!!!!
Leave the thing where it is!!!!
1.)remove the old brake lines.
2.)remove the upper and lower A-arms with the spindles attached.
3.)Get a set of arms with disk spindles attached.(72 and up)
4.)Install the newer upper and lower A-arms.
5.)install updated brake lines and hardware.
This will work for 1/2 ton 3/4 ton ect.
