Hadn't heard that one, and its not..er..intuitively obvious why it would work..something to do with a lack of self-servo effect when going backwards stops them over-tightening??
Or, more likely, because the back wheels don't do much braking going forwards, so reverse braking applies more load.
Anyway, had a bit of a fossick around, and found this...

"If the vehicle is equipped with self adjusting drums (most domestic vehicles from the 60′s onward do, my 1978 Ford Courier did not) take it for a drive. Self adjusting brakes work in reverse, in a safe place (large empty parking lots are great for this) back up briskly (about 10 mph), turn the vehicle in one direction, and slam the brakes. Do this three or four times per turning direction."
Stranger still. What's the turn for?
(maybe applying more load to the wheel on the outside of the curve??)
Anyway, worth a try, though it'll be challenging finding a large empty parking lot in Taiwan.
Or, alternatively, a 1978 Ford Courier.
