A: master cylinder. B: calipers. C: drums. The braking system in an automobile includes the master cylinder, calipers, and drums. These components work together to slow down or stop the vehicle.
Step-by-step explanation:
The braking system in an automobile consists of several components, including the master cylinder, calipers, and drums. The master cylinder is responsible for generating hydraulic pressure that is transmitted to the calipers and drums to initiate the braking process. The calipers are part of the disc brake system, while the drums are part of the drum brake system. Both systems work together to slow down or stop the vehicle when the driver applies the brakes.
