Those Huck 3/4 tons have a separate drum from the hub. Remove 2 slotted
screws to pull drum without disturbing bearings or hub. You will probably
need new linings if they are fluid soaked. A brake spring pliers with wire
hook removes and installs the return spring nicely. You may ned a hand impact
driver to remove 2 slotted screws. Put anti sieze lube on all pivots and
screws during reassembly. Cover new linings with wide masking tape to keep
clean during reassembly. Remove lock rings carefully so you can reuse them.
My Huck brake article in This Old Truck a few months ago may shed more light
on the topic.
