Brake Pad Wear Sensors (Electrical)

The electrical brake pad wear sensors are attached to (or part of) the brake pads. They will trigger a warning on the instrument cluster when the brake pads have worn down to the point of needing replacement.

Symptoms of Wear or Failure

  • Illumination of the brake pad wear warning indicator

Related Repair Advice

  • Ignoring the brake pad wear indicator may result in damage to the brake rotor(s), and in extreme cases, the brake caliper(s)
  • Electrical brake wear sensors should be replaced along with the brake pads to help ensure proper operation of the brake pad wear warning system
