Brake Wear Sensor Light On, But Brakes OK

[superporschefan]

So, I was taking of the wheels of my 2002 996 C2 and giving them a good cleaning. While doing so I used some brake parts cleaner on the rotors to help reduce some dust and take care of some trace squeal. Afterwards, I started her up, and my break wear sensor light came on...

Now, the pads are almost brand new (5000 miles) and no where near the sensor. I checked the connections, and they all look ok...

It's possible some break wear cleaner got onto the sensor, but I doubt it. I tried hard to avoid it anyway.

Any idea what might have tripped the sensor? Any thoughts on how I might test them?

Thanks in advance from a Porsche newb... :notworthy:

Disconnect each sensor one at a time and measure the resistance across the two connectors.

If they read open (infinite resistance) then they are bad.

Hi Loren - the weather cleared, and I just got around to working on this. I tested all four sensors and they checked out OK. I even disconnected each one, one by one to see if the light would go off, but no luck. Again, the pads are almost new. Weird, I know...

Any other ideas?

:huh:

Thanks in advance!

Disconnecting them would cause the light to go on. The brake sensors sense an open wire (or connector).
