Brake Pad Sensor Light issue

On my track car my brake pad sensor light had been coming on intermittently.

Ultimately, it came on full time.

I have plenty of pads so I started to look at the sensors.
The last time the pads were replaced, one of the sensors was damaged and had been replaced.

I checked my rear sensors, and they were loose. I plugged them back in to no avail.

Ultimately I ended up buying 4 new sensors thinking it best to replace the whole set just in case there was a balance/comparison mechanism going on.

I still have the brake pad sensor light on solidly.

Is there a way to query the brake pad sensor circuit to know which one it is complaining about? I have a durametric, but I don't remember that being a monitored event.

thanks,

Mike

Have you thought about shorting the sensors out?

Most track guys remove the sensors or tie them back. The sensors don't like the high heat that occurs when tracking. For those that inspect their brakes regularly, they really aren't needed. It is mostly for the non mechanical types that haven't got a clue as to what is making that scraping noise when they step on the brake pedal.

Wasn't sure how they worked

Ie how do you disable them, short them, or solder in a known resistance

If I recall correctly, there is just a wire in the end that breaks the circuit when it is worn down enough.

Strip and twist the 2 wires together, heat shrink & Ziptie the whole circus out of the way to the back of the strut.
Presto, no more dash light.

I melted the sensors on my previous Boxster just by driving in the Alps last year. This year I changed pads to a DS2500 which don't have the slot anyway and simply shorted them out as above. The rear sensors are still in and they didn't melt but if there is a problem you can do the same.
