Both brake pad wear sensors are wired in series so there is no way of knowing which one has failed without manual check or measuring.

Replaced leaky motor mounts.
Replaced bad and leaking oil level sensor.
Replaced torn intake boot.

Fun day. :)

If you push your car, when the fronts are worn you will notice less braking power.

Visual check is the way to go: sensors are front left and back right.

Best way to measure.

Just look through the wheel and see which end is touching the pad sensor. No pad left, you found your fault. :dunno:

The sensor is pretty pessimistic. Comes on at 3mm. If you drive a lot of highway miles that's 10,000 miles left.

10,000 miles with "Check brake linings" on the dash. My OCD kicks in and couldn't make it 3 days.

That's what tape is for. (or just twist the wires to the sensor). I've definitely driven at least 4-6k miles after a sensor lit up.

No way. I just can't ignore the obvious. I'm too much of a gearhead to ignore that warning.

If I have any warnings on my dash, I fix the problem.

It's just the "start" of pads are low. You can measure how much is left after you get the initial warning.

3mm is a very pessimistic pad wear value.

If you have 3mm of pad left, they are DONE. Some people might see that as "start", I see it as "end".
