You're right, I don't think there is much info on the front and rear drum brake setup.
Very easy to do. Hardest part is getting the brake cable set correctly.
What do you need to know? I'd be happy to take pictures for you or even a video.
Looks like a lot of stuff in there, but its really simple. Two pads, two springs, a pivot point and thats about it. The fronts have a few other parts but you don't need to mess with them.
First time I did it I knew nothing and it was pretty simple. Let us know if you need some help.
