That's a bummer and odd.
a) A 6K car should have no need to change shoes and it would have been cool to see the original markings if it was a 6 k car.
b) Odd because who the hell changes brakes for the heck of it. Check 'em, adjust 'em, and leave 'em unless something is bad or worn.
Yep. I am actually running the rear shoes that came on my car when I got it. Rust everywhere, wire wheel and paint everything, new cylinders, new springs. But kept the shoes. LOL. IIRC the last inspection was 1997. So they are over 20 years...
