done rear calipers,discs and pads on a 53 plate vectra last week and could have done with a small tweak on the cable,if your lever is on the right side of the centre consul then the adjustment is down in there,was pushed for time and didn`t manage to get it done and will have to have another look,pulled out the ashtray at rear and couldn`t see the adjuster from there but if you see if the top hatch has access then good luck with that.
