Melted Rear Brake Pad Sensor

[maj75]

I recently attended a DE at Homestead Speedway. It was my first DE and I had a blast.

Midway through the second session, the Brake Wear light came on. I thought it was odd as I had fairly new pads on the car, but I finished out the sessions with no issues. I ordered new pads and front sensors thinking that would be where the problem was. I finally got around to replacing the pads yesterday and to my surprise, the pads were all fine.

The problem was that the brake pad sensor on the passenger side had melted in the outer pad. The plastic housing on that side was deformed and the wire was exposed.

As I intend to do more of these events, I would like to prevent this issue in the future. Anyone have experience with this? Any ideas how I might prevent the problem? The pad and caliper are fine, the piston moves normally. Car is 2000 Boxster S.
