In the old days that I remember, there were two common kinds of emergency brakes: 1) a cable linkage to a mechanism in the rear drums that levered the brakeshoes essentially the same as when applied hydraulically (but only on the rear wheels) 2) a separate driveshaft brake mechanism. I don't recall the details --don't recall ever disassembling one-- but I vaguely recall it was ahead of the forward universal joint, so that it didn't do much braking (emergency or parking) if you lost a u-joint. 'course if you lost your forward u-joint (at speed), maybe you would do yourself in before having time to think about emergency braking. :-( How _do_ they do emergency brakes on a 4-wheel-disk system?
