See pic below. I realize it's dirty, but this is exactly how I removed this sensor out of the caliper. BTW, the sensor was NOT in its cozy spot where it belonged. Why? If you look closely, whoever changed the brakes last time decided the little spring clip that holds the sensor in place in the pad would perform better as some sort of tie-back for the wires. :rolleyes:

I have had several fail, not because they fell out but because the wires got pushed into the rotor and got cut. In the rear mostly. The other thing I have noticed is that when the light comes on on the dash, there is still usually plenty of meat left on the pad.

There are some people in the world that should not handle tools.

Apparently the sensor retainer clip on the pad plate baffled the mechanic! :thinking:

if you are careful, when you visually inspect the brake pads, like during a tire rotation, you can carefully position the sensor wires so they almost stay clear of the moving caliper.

I check them on every pm problem is ice,snow mud and whatever else gets up in there causes them to come in contact with the rotors.
