Brake wear sensor - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Tiga05 · 03-07-2018, 08:17 AM

After some spirited driving the brake pad light came on. I took off all four wheels and found plenty of meat on all the brake pads. Each of the sensor wires look intact as well. So I am looking for suggestions to resolve this.

If I buy one replacement sensor can I keep moving it to different corners until the light goes out? Do I have to drive it or will the light go out just by replacing the bad sensor?

Other suggestion? Thanks

If you got the brakes very hot perhaps doing a lot of downhill hard braking you can melt the sensors.

Light will go out when you replace the bad sensor. I melted a sensor coming down the hill into turn 10a at Road Atlanta and my brake wear light came on, got my heart rate up...

If you pull the brake pad wear sensor end out, you will probably see that one of them is melted into a blob, and that is probably the bad one, and is 99.999% one of the fronts.

I don't run any sensors anymore, I clipped about 1" from the end that connects to the wheel carrier, stripped the two wires, twisted them together and insulated them, and I just check my pads visually. Since I have the wheels off all the time due to track work and brake bleeding, it works for me

I've actually got an extra sensor I can send you if you PM me your address. IF I can find it... It was only $5 or so from R O C K A U T O . C O M.

This is what a melted brake sensor looks like...

What Steve said. I've jumpered mine since it became an annoyance for me.

x3 on shorting out... best solution by far

Good luck
