I suspect the spring which retracts the emergency brake shoes has broken or come detached as I am getting some brake squeak at low speeds which coincides with driveshaft rotation. Anybody mess with that system? Doesn’t seem like it is a pressing fix. Is there a reason to think otherwise?

Other than the spring if broken may get caught between the linings and drum badly scoring it.

Still the same deal. Noise while you are driving around will tell you a lot if something is getting caught. Reversing back at that point may shift it again to not be a problem.
Not that hard to investigate. Remove the four nuts that hold the tailshaft to the handbrake drum, slide that end of shaft back. Slide hand brake drum off, remove parts, drum back on, tailshaft on and your done.

If yours has a Centre bearing, such as mine does being a dual cab with the 2 tailshafts, then I've always had to drop that as well to get at the handbrake, easy job, only 2 extra bolts if needed. The brake is a simple mechanism, easy enough as Dan said to take a look and rule it in or out as the culprit.
Good luck.

Okay, as "canter tourer" says two extra bolts.

Without disassembly I discovered the exact problem. The pin/spring/90 degree twist washer which attaches the right shoe is no longer tight. I was able to determine this by grasping the pin at the outside of the backing plate and moving it around. The left side pin is completely tight. Anyone know if generic pins/springs/washers will work or are these Fuso specific?

They may be Fuso specific but saying that they look like normal pins with a U-shaped wafer washer (could use springs and washer instead). This I have seen in other brake setups. The pin length would be the biggest concern.

Thanks. Tom’s Truck Parts sells the whole assembly so I’ll order everything and get it up to snuff as the truck has 230k miles on it. Probably wait until I get home to do it. or maybe to a friends house since he has a lift. I stopped using the emergency brake and the squeak/squeal has pretty much gone away. I was carrying a nice pair of aluminum chocks which are an adequate substitute except for starting out on a steep hill.
