I used TSM disc brake conversion. Came with all the parts, brackets, lines, etc.they use GM parts.
Bolt on. they have e-brake versions. I used All Pro's flange mounted.
Only thing I still need to do is 1 inch bore Master. Braking bias is controlled by stock 'yota brake thing on the frame. what's it called? Just played with it till I was happy. I forget but I think it's, arm up more rear, down is less.
