Thanks for the replys guys,

I was looking under the car at it yesterday and i did replace the cresent at the same time ( its part of the cable assembly) it was just such a long time ago that i fitted it i ad forgotten

Anyway was playing around adjusting it and have found that when you adjust it right up to give a good handbrake, under load the adjuster slips up the outer cable so unless i make up a clip/braket to hold the adjuster on the threaded outer coating it will need a new one. Could be a faulty cable i suppose as i dont think i bought a genuine ford item at the time.
