Worked in Central London today, so when I got home eventually I had a cuppa tea, and Google'd setting the handbrake on one of these. FAIL.
So I referred to the Haynes book Paul the seller had given me, and managed to figure it out.
You can either do some setting on the handbrake lever or you have a proper adjustment screw on the rear hub area.
Once I had the car high on a jack, I did the two sides and believe we now have a handbrake worthy of an MOT.
I also removed the rear Fog light ( and hope it does not constitute a fail)
Some spares landed today as well, and will get fitted next weekend.
Fingers crossed for the MOT test tomorrow.
