I am searching the brake service instruction on ATE site and found the abbreviation, that I can't decipher. Apparently, it is opposite to the passenger car, thus it is relative to heavy trucks, buses, etc, but what does CV letters stand for?
I didn't know this, but after a quick search it looks like it stands for Commercial Vehicle.
which says - "Europe is the global leader in the Commercial Vehicle (CV) industry and in 2014 vehicle registrations grew by 10.8%, with vans, buses and coaches all increasing significantly"
which says - "xxxxxxx is a leading aftermarket supplier of pads to fit commercial vehicles"
