I'm curious about copper in the brake fluid myself.

I took my GTX to the tire store across the street for a State safety inspection. The first thing the ape mechanic did was unplug a bunch of stuff under the dash looking for the OBD plug. Then they couldn't figure out how to enter the VIN in the state system because it only had 13 characters.
I ended up taking it to the place across town where I usually go.
