I am wanting to adjust the handbrake on my '55 plate Stylance, but can't find the adjuster. I have tried the usual place under the handbrake lever, but there is a plastic cover which slides up with the lever, which prevents any adjustment there. I have also checked underneath, and the cable goes through the floor under the back seats. The only other place I can think of is under the centre console binnacle. Is it under there, and do I have to somehow remove this, to get at the adjuster ??
