One step closer to my 928 mechanics degree - but still brake pad warning.

My guess is that one of the sensors connectors is not fully seated or has a broken lead wire. Also, the sensors are easily damaged when prying them from the pad. I would check them over again, and if nothing is obviously wrong, bypass all of them at the connector temporarily and drive around. If the warning light is still on, then the problem is more central. If the warning no longer trips, then remove one bypass wire at a time until the warning returns. Then you will have located the culprit (well, one of them, at least - the final test is to replace that jumper and remove all the others). Replace that sensor.

Yes, I have a multimeter - You know, one of those a really cheap ones from Harbor Freight... Neer used it ,though.
We replaced the front sensors, even though the old ones had not been touched. We installed them so the thicker area points towards the rotor, and the thinner awayy from it.
Last night the warning came on at the end of our test drive. Today, no warning came on at all.

An intermittent fault may be hard to find with the meter, but give it a try, wiggling the wires a bit. As to the thicker side orientation, they only go in one way, so I'm sure you got that right. You need to check the back ones. There's agood chance that's where you will find a loose connection. Those plastic shells that snap over the connectors are a bear to get one sometimes and can pop open.
Also, if the old pads are OK, you can break the glaze with emery cloth. That will sure help to eliminate the squeaky brakes.

I might just watch it for a few days. We're going to be very busy this week - I doubt I'd have time to mess with it over the Thanksgiving weekend.
The good thing is: The pads are good all around, and it's not a safety risk to drive. Maybe some time next week we can have a peek at the rears.
