Black1,
I was thinking the very same thing about disconnecting the battery, but I didnt do it while replacing my sensor tonight. I wanted to see what it would do. So anyway, I replaced that rear sensor and went for a ride. The ABS light came on but the pedal never pulsated no matter how many times I pressed the brakes.
I do not know if I fixed it, so I will drive it for a couple days and see if the pedal acts up. The rear ABS sensor that came out did have small metal fragments stuck to it.
thanks,
Rick
