I'm pretty sure your jimmy's drum setup's the same as all the fullsize
chevys i've worked on, if so, just take off the rear wheels and you should
be able to wiggle the drums off the lugs, after that, just pull the spring
off and pull out the old pads.
Four wheel drive, rear drums. As near as I can tell the drum and the lugs
are one unit. Once I remove the wheels there is a slight bit of play and
the lugs move with the drum. There is a round keeper of sorts that is
middle of drum, center axle. The keeper has two raised protrusions that
look like you would use a hammer and chisel to turn. The protrusions have
stamped on them "S" on one and "M" on the other. I don't know if they turn
or not. In any event, if they do, a special tool would be required?
Thanks, Mr Ranger
Lugs are part of that round protrusion. That's the end of the axle
itself. The drum comes off separate from the lugs and that round
center. I'm going to assume you don't have the e-brake set while
attempting to remove the drum. If you do, release it and the drum may
pull off. What sometimes happens is that the shoes wear into the
braking surface some, causing a ridge on the inside edge of the drum
(the open edge once the drum is off). You'll need a tool to get in
through a hole in the backing plate to back the adjuster off and be
able to pull the drum.
Finally, Company gone, car race over, went to work on brakes. Removing the
drums was just as described. All that was required was a little persuasion
with a big hammer and a crowbar as suggested. Thanks a lot guys.
