If a car has disc brakes in the front and drum brakes in the back, how many brake rotors does the car have?

To determine how many brake rotors a car with disc brakes in the front and drum brakes in the back has, it’s essential to first understand the components involved in these braking systems.

Disc brakes utilize a rotor, which is the large metal disc that the brake pads clamp down on to create friction and slow down the vehicle. In a vehicle equipped with disc brakes in the front, there would be one rotor for each front wheel. Since most cars have two front wheels, this means there will be two brake rotors in the front.

On the other hand, drum brakes do not use rotors. Instead, they use a drum that encases the brake shoes which press outward against the inside of the drum to create friction. Because of this, the rear wheels, which have drum brakes, do not contribute any additional rotors to the total count.

Therefore, the total number of brake rotors in the car is comprised solely of the two rotors present in the front for the disc brakes. This leads to the conclusion that the car has a total of two brake rotors.
