Final answer:
Disc brake systems and hydraulic systems are crucial components in operating vehicle brakes.
Explanation:
A disc brake system consists of a brake disc, a caliper and brake pads. When the brake pedal is pushed, it moves the input piston, which pushes hydraulic oil into the output piston.
Car disc brakes also use a caliper. This caliper exerts a squeezing force on a disc behind the car wheel.
Hydraulic systems are used to operate automotive brakes, hydraulic jacks, and numerous other mechanical systems.
