A) computer
B) gears
C) hydraulics
D) fuel lines

Accepted Answer

The force applied to the brake pedal is transmitted via hydraulics to the brakes at the front and rear axles. Hydraulics use fluid pressure to transmit force, which is why brake fluid is an essential component of the brake system. Gears and fuel lines are not involved in the transmission of force to the brakes, and while some modern vehicles may use computer-assisted braking systems, the basic mechanism of force transmission is still hydraulic pressure.
