If the brake pads are not worn out check the backing plate. It is the thin metal plate behind the brake rotor, sometimes it will get bent and rub on the brake rotor.
Not usually, unless the CPU is less than 6 months old.
If the vehicle itself has ABS, the entire braking system will have it.
Check the pipe inside the U part of the axle housing itself. They like to break out by the edges.

The expiration date of your driver's license is typically printed on the card itself.
The code C121C means that there is a problem in the anti-lock portion of your braking system. The code itself reads "Torque Request Signal Denied".This is a safety issue, Under hard braking the anti-lock could FAIL .
On the firewall, driver's side, right in the corner closest to the driver, all by itself.
Redundancy, if one fails the other is probably still working and can stop the vehicle by itself.
The distance required for lawful brakes to stop a car traveling at 20 miles per hour typically ranges from about 25 to 30 feet, depending on factors such as road conditions and the vehicle's braking system. This distance includes the reaction time of the driver and the braking distance itself. It’s important to consider that these distances can vary based on environmental factors and vehicle maintenance.
A display driver is required for the system itself to display anything, so essentially no, there isn't.
A scanner is both hardware and software, the device itself is hardware (all devices are hardware) but the driver(a program) that runs it is software.
