What action should be taken on the other side of the vehicle when replacing brake pads after a collision?

When replacing brake pads after a collision, it is important to address both sides of the vehicle for several reasons, including safety and performance. The correct action involves replacing the same components on the opposite side, as this ensures uniform braking performance. When one side of the braking system is serviced, the other side should be treated similarly to maintain balance in the vehicle's braking system.

Collisions can cause uneven wear or damage to brake components that may not be immediately visible, and replacing components on only one side could lead to reduced braking efficiency and potential safety hazards. Ensuring that both sides are equal in terms of wear and performance helps to create a more stable handling characteristic and prevents issues related to pulling or uneven braking.

The other actions, such as polishing the rotor or measuring the pads for serviceability, do not address the critical aspect of restoring uniformity in the braking system after a significant event like a collision. While these might be valid maintenance practices, they do not directly relate to the necessary response on both sides of the vehicle after an incident.
