First of all Welcome Aboard. Be prepared for the insanity to set in.
In order to change your rig to disc brakes you would be best to change the entire rear end which is not really that big a deal. The real fun comes with the parking brake. The disc brake units require a drum brake mounted on the rear of the trans. That involves a new tail shaft housing, backing plate, drive yoke, drum shoes, and the cable and linkage to operate everything. Some parts like the drive yoke can be very hard to find.
When you go through your brakes put new cylinders, shoes and mounting hardware and with the number of miles usually put on these coaches you will be good for many years.
