Thanks Mike. I’ve pondered this for a long time, 12 years in fact, and confess to continuing curiosity. Whatever the cause is, it does happen. I for one was relieved to compensate (!) for the problem with an Arctic special – possibly the most effective mod available!
However, at the risk of boring more than a boring thing, I remain sceptical of the cause. My apprenticeship many years ago included analysis of various substances and the loads causing stress fracture that might be expected – specifically in metals.
The load applied at the handbrake/fulcrum, necessary to stretch that rod would possibly result in catastrophic failure elsewhere. Beyond normal human endeavour!
Until a proper lab test is taken I can’t believe that sturdy rod yields to the puny tug from 6” of lever travel! If that could be explained I’d be very happy!
