hi folks..wondered if any one can help....6 months ago handbrake lever would come up but cables would still be slack even when tightened...and brake didnt engage one bit..when it went for MOT garage said it was just something seized up and they fixed it...it has now happenned again...lever comes up easily, cables slack,no brake......is it that something has seized with the calipers open or something like that? is it fixable?replaceable? any views on it would be cool
