With more people forced to stay at home due to the covid-19 pandemic, vehicles are setting for long periods. One of the most common conditions is an accumulation of corrosion on the surfaces of the brake rotor.

Andrew Markel discusses the procedures to remove surface rust on rotors. This video is sponsored by ADVICS.
