The handbrake on my dad's 80 has always been a bit weak and problematic but this time it seems to have become non-existent. I remember reading somewhere that it is a bit of a weak point on 80s. Is it a case of just keeping on top of it or is there aftermarkets kits or parts to beef it up a bit? I also have read on this forum (but can't seem to find it) a thread where someone has detailed the proper tensioning of the cable to ensure its set up properly. Any advice gratefully received!
