Handbrake tightened to 31mm! How bad is it ?

Hi,



My handbrake sufferes from the stretched splitter, and when I tried to get to it, I found the nut was tightened to 31mm. (and it was stretched as expected)



When I try to release the lock nut, it has a springy feel, and it like ticks over,...



What should I do ? (Haynes only say _not_ to do that)



New handbrake, oil on the thread, or just turn and see what happens ?



-And should there be tension on the brake when I try to loosen it ?



Thank you for your time,
