A few post-mortem questions for you...

1. Did the brake pad wear indicator "flicker" or come on solid when brakes were applied while deaccelerating?

2. Did you notice pad wear (especially the fronts) that was down far enough to trip the sensor attached to it?

3. The pad wear sensor is indeed yellow, but does the icon look like a set of concentric circles with a dotted outer circle (three hashes, each side)?. Is it to the right of the red BRAKE indicator?

If you answered yes to all of these questions, then possibly, the sensor(s) aren't installed properly, Take care to route the sensors through the spring clips in such a manner that the insulation is not subject to kinks or anything that may breach the insulation, cause wire-to-metal contact, and set off the light. This happened to me once upon pad installation.

BTW, if the light you are referring to is the one next to the ABS light, then that is the "bulb out" indicator, not the brake pad sensor.
