Which wheel-braking arrangements are included in this classification?

Question

Wheel-braking arrangements can be:

Answer choices

1. Disc.
2. Drum.
3. Combined.
4. All of the above.

Explanation

Cars use disc and drum brakes at their wheels. In this educational classification, a combination, such as front discs and rear drums, is called a combined system.

Choose all of the above. Here, “combined” means a mixture of mechanisms on a vehicle, rather than a separate third type of wheel-brake mechanism.
