B. generate additional stopping power.
Explicación
## Step 1The problem is about understanding the differences between two types of brake systems: the leading-trailing crum brake system and the duo-servo (self-energizing) drum brake system. The leading-trailing crum brake system is a type of drum brake system where the brake shoes are arranged in a way that one shoe leads and the other follows. The duo-servo (self-energizing) drum brake system, on the other hand, is a type of drum brake system where the brake shoes are arranged in a way that both shoes lead.## Step 2The leading-trailing crum brake system has a tendency to lock up the wheels during braking, which can lead to a loss of control. This is because the leading shoe is the primary brake, and the trailing shoe is secondary, which means it doesn't contribute much to the braking force.## Step 3The duo-servo (self-energizing) drum brake system, on the other hand, generates additional stopping power. This is because both shoes lead, which means they both contribute to the braking force. This additional stopping power is what makes the duo-servo system more effective than the leading-trailing system.
