Stripped the back brakes down on Ruby again this morning, as previously noted the springs were new and they are very stiff and difficult to fit and remove, so think they should be ok. All parts appear in good order, all levers are free and return without any issues and brakes return without sticking.
I backed off the cams to lesson contact between brake and drums cleaned everything down and boxed it all up.
As soon as I tried to reverse out of the garage the brakes locked again!!
Drove around locally and all seems ok going forward but again locks up in reverse.
Stripped it all down again in the afternoon and noticed the drums tighten on the shoes once the three set screws are fitted. So filed all the excess lining material overhanging the brake shoes, bevelled the the linings along the edge that could contact the drum in the inner corner.
Although I had previously filed the front and rear ends of the linings to prevent grabbing I ran the file over the edges again.
Set her up so the cams were as far out as they could be and boxed her up, unfortunately with the same result, great going forward but whilst the brakes didn’t quite lock up this time, they did come on and reversing was not easy.
The new linings I have are from one of our suppliers but are different from the previous linings I had, they do seem to have a higher coefficient of friction then the previous ones.
So I’m back to square one again.
Any suggestions would be much appreciated.
Cheers
