The rear brake pad wear sensor monitors the thickness of the brake pad friction material. When the pad wears down to a predetermined limit, the sensor alerts the vehicle’s onboard systems (and driver) via a dashboard indicator, helping prevent damage to the braking system and maintaining safety.

Function:
• Detects rear brake pad wear
• Signals brake wear status to the dashboard
• Helps avoid excessive pad wear or rotor scoring
• Supports timely and safe brake maintenance

Driving with worn brake pads without proper indication can lead to:
• Reduced braking performance
• Longer stopping distances
• Scored or damaged rotors
• Risk of brake system component failure.

A functioning brake pad wear sensor helps maintain optimal brake performance and prevents unnecessary damage to expensive brake components.

When to replace:
• Rear brake wear warning light illuminates
• During rear brake pad replacement
• If sensor wire, connector, or clip is damaged
•  When replacing rotors or servicing rear brake hardware.
