GOT IT !!!!!!
Managed to see the broken cable from lever end today. It was in the outer sheath so had to cut 1/4 inch of outer off to grip and got it open.
Thing is..........
I have read that a Tandem bike cable will work, but its 1.5mm dia and the original i have removed today is 1mm dia................ CONFUSED
Wondering now if i should go for original replacement from Stealers
