Hi, I have done the rear sections this year. Very easy
Basically you want to jack up the rear, remove the wheels and drums. I removed the end closest to the cab first by removing a split pin on the pivoting section.
With that end loose you should be able to get some slack on the cable inside the drum and remove it from the lever.
The cable outter can be removed by squeezing and pushing on the end that's inside the brake plate. I used some pliers, but knocking a socket over it might be better. I had 2 brackets, 1 on the leaf spring and one near the gas tank. Be prepared to replace the bolt on the one on the spring
