I hope this will be of interest and assistance.
When preparing for the MOT (109,550 miles) I replaced the nearside front lower wishbone assembly (what a shame the old one is scrap) overhauled the front and rear brakes with new discs, pads and hand brake shoes and changed the rear brakes back plates on both sides as the original ones had corroded.
The whole job was fairly easy but what caused the most difficulty was changing the back plates; the hand brake cables have a metal ferrule on the end which locates in a metal tube which is part of the back plate, the ferrule had corroded in the tube and was impossible to remove, the only way to get it out was to remove the tube from the back plate by chiselling it out and then carefully hacksawing a slot in the tube and prising it off the ferrule.
On completion I applied copperslip to the ferruel so if I ever have to remove the cable or change the back plates again it will be a lot easier.
By the way the car passed the MOT with just one fault; nearside front indicator, the one in the wing just under the wing mirror, the orange paint had come off the lamp.
