At a push the handbrake shoes may have been dislodged. Or the adjuster has become loose allowing shoes to wedge on drum.I thought so too, but the NFU engineer (my insurance) cannot see how it would be. Currently transferred to Inverness 4x4, as I trust Hamish (but not the dealer in Inverness). I told them I thought they should choose a garage for repairs who could repair everything!
Thanks. 4x4 said it was coincidence, corrosion and shorted which melted cable - trust them. Thank you for helping.Welcome to the forum
Any luck with this?
