Both A & B are correct
Two technicians are discussing the reason that the brake fluid level in the master cylinder drops.
Technician A says that it may be normal due to the wear of the disc brake pads. Technician B says that
a low brake fluid level may indicate a hydraulic leak somewhere in the system. Which technician is
