Hi all, my first major project on my recently acquired '68 520 was to redo all the hydraulics and related brake adjustments. I tackled the master cylinder and front brakes first and that seems to have gone OK, everything went back together and I have a good understanding of how the brake adjusters are supposed to work.
When I went to do the rear brakes I removed the brake drum and found them in really poor shape, there was metal on metal and lots of crud. Upon closer inspection something didn't look quite right, here is a picture of what I found.
After much head scratching and looking at the two service manuals I realized that they had installed the brake shoes upside down! So I cleaned everything up as best I could, and reassembled it to look like so.
Now, I know these are still not quite right, first off, I missed hooking the small spring on the brake adjuster tang, but I have ordered all new hardware and brake shoes, so I will fix that when replaced. The one thing that I really need help with is how the emergency brakes go together, I am missing the piece the manual calls "Lever, toggle (L.H.)" and am not sure I have the "Link Extension" that connects to the cable placed properly. Does anyone know where I can get the missing piece and a picture of how these brakes should look stock. The exploded diagram is great for accounting for all the pieces, but I feel like a picture would clear a lot up especially considering I have never seen what a correct installation looks like. Is there a toggle lever on both sides? I haven't done the right side yet, but am expecting the same thing there too.
I have searched around and have most of what I need as far as information goes, but the one thing I am missing is a good picture of how the rear brakes go together because most forum posts no longer have the pictures included. Thanks in advance!
