Ok, back on track. Of everything that was seized/rusted on the car the brakes provided the biggest challenge. Why, because I couldnt get the bloody wheels off. Car was up on stands, out came the wheel wrench, but when applied to the nut it turned but didnt unscrew. The nuts were so rusted onto the studs that it was the stud that was turning. What now. I could have taken the hub nut off and pulled the whole wheel/drum/hub off in one go, but getting at the split-pin etc with the wheel in place was a mission, and the brake shoes may have got in the way. I then tried my rattle gun on full power to see if I could trick the nut into undoing......but no, all that happened was the stud reamed out the hole in the hub even more making everything really loose!!
Eventually what I did was to get my small right-angle grinder with a very fine cutting disc on and cut a slot into the end of the stud into which I could tap a decent screwdiver, which I held with vise-grips while working the nut back and forward with copious amounts of WD40 squirted around......like a one-armed-paper hanger.
Victory......needless to say I lubricated everything before reassembly so the next person to remove the wheel will have a fair go, and be able to use the slots if necessary. Not me.
I tell you, Ive lost a bit of sweat over this machine, hope it is all worth it.
