Difficulty: EasyBraking Systems

In an automotive drum brake assembly, which component is forced outward against the rotating drum to generate friction and slow the vehicle?

  1. A
    Brake pads
  2. Brake shoesAnswer
  3. C
    Brake rotors
  4. D
    Caliper pistons

Answer

Brake shoes are forced outward against the rotating drum to generate braking friction.
In a drum brake system, hydraulic pressure delivered to the wheel cylinder forces the curved brake shoes outward into direct contact with the inner friction surface of the rotating drum.

Step-by-Step Solution

1
Identify the specific brake configuration described in the stem.
The question specifies an automotive drum brake assembly.
Drum brake and disc brake configurations utilize distinctly shaped friction components.
2
Select the friction component designed to expand inside a brake drum.
Brake shoes are curved metal structures lined with friction material positioned inside the drum.
When hydraulic pressure enters the wheel cylinder, its pistons push the brake shoes outward against the drum.
