How can improper adjustments of the brakes affect performance?

Answer: C — They can cause uneven braking and increased wear

Improper adjustments of the brakes can lead to uneven braking and increased wear on brake components. When brakes are not correctly aligned or set, some wheels may engage more forcefully than others, causing a disparity in braking power. This uneven distribution can lead to a loss of control of the vehicle, especially in critical stopping situations or during cornering. Furthermore, if some brakes engage sooner or with more force than others, it can result in excessive wear on those specific brakes while others may exhibit reduced wear. This inconsistency not only increases maintenance costs but also compromises the overall safety of the vehicle. Well-adjusted brakes provide balanced stopping power, which is crucial for effective and safe driving.
