Upgrading the front brakes means larger wheels so they can fit.
With the 503L shoes after you run them for a while you can shim out the lower shoe rests. When you check them later you will see the wear at the top only and with any heavy braking they will overheat and possibly crack.
When you fitted those new backing plates did you file-grind the rust ridge away from the bearing housing? Did you get the plate to sit perfectly flush before bolting? The shoes sitting tapers indicates the backing plate was not properly seated and when bolted in place it became distorted. Might also explain the rubbing and damage to the inspection plug.

I dunno. It's all just such a giant crap shoot. Aftermarket parts I mean.
Like you'd think there would be standards like ID of new drums, shoe lining thickness etc. that work in harmony.
Hypothetically speaking, if a brake parts maker is going to make shoes better suited to the Vanagon, like closer to OEM, one would hope that same company would make both the shoes, drums, hardware etc.
Yes, I'd think that I'll have a less than ideal contact patch, initially anyways.
I think the real issue with the pre '86 brakes, for me anyways, is brake fade.
I have the later style steering knuckles. That may be the next project though its just a bunch more work.
The good part is I've learned, I hope, a fair amount. The current shoes are still bedding in but pedal height is getting closer to normal. It was nice to hear both adjusters working.
Reinstalling the GW shoes is not really an option it seems; I just couldn't get them to fit w/o having them heat up even when brakes weren't being used.
But maybe my lack of experience with brakes is the issue. Hard to say.
Neil.
