Nope but I would not trust any brake bracket shimmed with washers!

Operationally, no different from spacers. In fact, that is all a washer is.

True statement.
Proper grade bolts and their tightness are more important, as they are subjected to shear forces under braking.

So, the institutional memory is a fail on this one?

No idea, but it absolutely looks like a caliper mounting bracket...

If you want good quality washers, ARP sells washers that are flat, without burrs, of consistent thickness, and good metal.
The washers in the photo are not ARP, but I am presenting a quality alternative.

The bolts in the photo have no markings on their heads, so they are most likely rubbish.
In most cases (such as this one), bolts are more used to clamp two objects together (with some washers in between in this case).
Shear is then transmitted between the two objects via friction. Clean and rough (sandblasted is good) surfaces help to enhance friction.
Depending on the amount of shear force to be transmitted, and the grippiness of the friction surfaces, the required clamping force can be estimated.
From the required clamping force, the size and grade of bolt needed can be found.
The bolts themselves are not loaded in shear.

The bolts are grade 8 - just slightly visible. No markings would be hardware grade.

I believe that's for the 13" brakes but I've never seen that particular kit before.

Thankfully finally someone on this forum understands bolts are never designed to transmit Sheer forces but to apply clamping forces...Hallelujah. Still, keep that ganky brake adapter off the roads near me, have a proper spacer added and welded in so that the bolts can do their designed job of Clamping. that adapter looks like going all the way to 95% and fukking off at the last bit.
