If only one brake pad is replaced during routine brake maintenance, the result is that __________.

Replacing only one brake pad can lead to unequal braking because the new pad will have a different coefficient of friction compared to the older, worn pad on the opposite side. This difference can cause the braking force to be distributed unevenly when the brakes are applied. As a result, the vehicle may pull to one side during braking, which can affect control and increase stopping distances.

Balancing the wear and material of brake pads on both sides of an axle ensures that the braking system functions smoothly and uniformly, reducing the risk of handling issues or accidents. Keeping brake pads in similar conditions ensures consistent grip and performance during braking maneuvers.
