'88 Grand Wagon brake job

My '88 Grand Wagon which I've had since '90 has served me well but I've 
gotten to the attitude that I really don't want to spend any more money on

it. I fixed a door lock and a power window on it recently, so I want to 
start to do these things myself. My mechanic told me a year ago I needed
new 
rear brakes. In fact, he said the right rear drum was perforated price to 
fix $400-$600). I have a two car garage and a fairly good mechanical 
affinity. I want to rebuild the rear brakes myself. I so I'm wondering if 
this is something I can do myself?
