It's probably buggered mate.
I'd just chuck it in the bin if I was you.
Know what i'm sayin' yeah?
LMAO!! Another classic!

I wouldnt worry about that too much, a handbrake normally setup for 5clicks, so solid both sides for 4clicks is damn good on age of vehicle you have.
Only thing if your picky to do is remove drum of the one that takes 4 clicks and manually 'click out' the shoes a bit, not too much else you wont get the drum back on!! But its a tricky little job and you get fraction too much and the shoes will rub too much etc.
If i was adjusting your brakes, I be well happy with 4 clicks solid both sides!!
