Automotive Service Excellence (ASE) Brakes Certification Practice Exam

Low tire pressure can significantly impact braking performance in several ways. When tire pressure is lower than recommended, the tires can become under-inflated, which affects their contact with the road surface. This reduced contact can lead to increased stopping distances because the tires may not be able to grip the road effectively during braking.

Under-inflated tires also tend to flex more than properly inflated tires, altering the vehicle's handling and response to steering inputs. This can result in decreased vehicle control, especially during hard braking situations or when navigating turns. In essence, both stopping distances can increase and control can be compromised due to the lack of optimal contact between the tires and the pavement.

The other options suggest either positive effects or no impact on braking performance, which does not reflect the reality of how low tire pressure interacts with vehicle dynamics. Proper tire inflation is crucial for maximizing braking effectiveness and overall safety.
