This is a genuine TOYOTA brake pad wear sensor, part number 90947-02E85. It is a crucial component of your vehicle's braking system, designed to provide an audible or visual warning when your brake pads have worn down to a critical level. When your brake pads reach their minimum thickness, this sensor makes contact with the rotor, triggering a warning light on your dashboard. This early alert allows you to schedule brake service before the pads are completely worn, preventing potential damage to your rotors and ensuring your vehicle maintains its stopping power. Installing a genuine TOYOTA sensor guarantees compatibility and reliable performance, maintaining the integrity of your braking system as designed by the manufacturer. Regular inspection and replacement of this sensor, along with your brake pads, are essential for safe driving.
