What is a break pad sensor?

A brake pad sensor is a component of a vehicle's braking system designed to monitor the condition of the brake pads. It typically consists of a small electrical device that triggers a warning light on the dashboard when the brake pads wear down to a certain level, indicating that they need to be replaced. This helps ensure safe braking performance and prevents potential damage to the brake system. Some sensors may also provide real-time feedback on pad wear, enhancing vehicle maintenance awareness.
