You mean like this? I had wound the adjuster off at this point)
This was the adjuster on my current ZT. The handbrake held ok but whilst I was replacing the carpet I fitted a stainless steel compensator that I had converted. I had a lot of trouble with the handbrake on my previous car, so I fitted one to that and it was good as gold after that.
I remember my dad having a Renault 25 with combined handbrake within the rear callipers, my dad didn't do many miles so got quite adept at removing and cleaning up the rear brakes.
