For those of you out there wondering why your parking brake doesn't work... Despite some of the prevailing opinion out there, it turned out that the rear cable (most likely original to my 72) was indeed stuck within the sheath and wouldn't budge. Inactivity of the parking brake (I assume from the stuck cable) then left the actuator arms stiff from non-use - nothing a little penetrating oil and grease wouldn't cure.
Don't overlook the cable - and use your brake occasionally!
