which of the following primary components of the disc brake system uses hydraulic pressure from the master cylinder to apply the brake pads?\n\na. rotor\n\nb. caliper\n\nc. proportioning valve\n\nd. brake pads
Answer
Brief Explanations:
The caliper is the component that uses hydraulic pressure from the master - cylinder to squeeze the brake pads against the rotor. The rotor is the rotating part that the pads press against. The proportioning valve is used to regulate brake pressure. Brake pads are what make contact with the rotor to create friction for braking.
Answer:
B. Caliper
