need A65 brake drum spec

[StanR]

I've gotten my 1966 A65 Lightning to the point of registering it with the California DMV. It"s been a long process due to collecting parts and paperwork to get it to this point. Right now I've got a major hurdle. Due to it's having been a salvage vehicle (then put on non-operation over 20 years ago) I need to get a Vehicle Safety Systems Inspection. The problem is to get it done I need the OEM maximum wear specification for the brake drums. I've got the digital copy of the factory workshop manual that doesn't specify other than 8" front and &" rear drums. Would a Haynes or Clymer manual have such a spec? Has anyone run into this issue? California started this inspection program in June of 2024, so it's relatively new.

Have you looked inside the drum? Some have a max limit number cast in.

From my experience Haynes and Clymer manuals don’t have anything not in the triumph manuals. I’m sure BSA is the same.

I just checked the front drum, no such luck.

Just talked to them. As far as they know there is no such spec. Guess I'll push the California Bureau Of Automotive Repairs for a solution. I'll keep you updated.

then the inspectors cant know if the drums are out of spec. there would have to be a standard industry spec. although dunno how that could even be applied. worst case is buy new drums and show paper work of purchase.

Thanks to the computer age they have to submit the inspection on a computerized form which will not let them complete it without a specification, so paperwork for new drums would not help.

Can you measure yours and give them that number as the spec? Sounds like it's only a box that needs checking, nothing serious in your case.
