I've been in Melbourne for a few days so now home and back to the story.
I started to strip down the rear diff. I said before that the rear diff was the Lynx Achilles heal. I located another diff assembly at Childers, a town in Central Gippsland, which had been used under a farm trailer. It was pretty complete but had had the spring hanger bases moved about 1" inwards. Still it was better than nothing. More about that diff shortly.
I went and saw Andy Seymour, 'The Brake Place Berwick' who fitted new brake linings to all 8 brake shoes, and turned out the brake drums to suit.
Both front and rear were done. Andy also pressed into place the bearing cups for the new bearings. All the bearings were purchased over the counter at the local bearing shop where they were all in stock.
He also supplied the flexible brake hoses from the rough samples I had. You might notice that I marked everything so that I knew what went where on re-assembly.
The complete rebuild of the brakes cost me a few bob but at least I know that I will be able to stop OK.
Regards Rick.
