Asbestos in brake pads was banned as a factory item for car manufacturers. No cars are allowed to come new with asbestos in the pads, it was a solved problem for a decade. It was allowed for replacement pads only(until last year when it was banned entirely).
That’s a federal crime. If it’s for your personal or household use and under $200 you’re fine(unless you’re coming from China).
Doesn’t seem like a good time to fuck with border control.
