About to start putting the front brake drums together and I just miced the drum thickness (where the shoes rub against) at 6 different locations. They all miced out between 0.186 and 0.189 inch. However…I can’t find any reference as to what this thicknes SHOULD be. Does anyone know what it is? Don’t want to assemble everything only to find out I’ve got to get new drums and then mess everything up taking it all apart again.
Thanks.Allen Caron

I have no idea. That should be in a shop manual though. Might call a shop that machines brake drums and ask.
I have thre different shop manuals and none of them cover that detail. It’s not even in the Muir book. Will have to drop in on the Samba crew. Perhaps one of them.

"If one thing matters, everything matters" - from the book The ShackSamba>65 rear brake drums:
wear limit for rear drums are 231.5 mm (9.114″)
Wall thickness should be a minimum of 4.0 mm (.16″)Here’s what I got from the folks on the Samba. It pretty much says what Royal did.
There is no spec for drum thickness, but there is for inside diameter, which
is how brake drum wear is measured. The specs are in the Bentley manual,
and the maximum I.D. should be cast or stamped in the brake drum
itself.Allen Caron
