remove front brake on 86 4wd

i have recently purchased an 86 1 ton 4wd with warn hubs and i need to remove the brake assembly to investigate a noise i believe to be in the bearing. before i go get a tear down book i was wondering if anyone knew of a site that had diagrams of this sort or had any advice about this dilemma

 

chiltons manual or the like from your local auto parts store is best bet
