[quote=FrenchBoy;5578411]I am unsure why you need a large pair of pliers to remove the retaining clipsQUOTE]
I was the poster that suggested the big pliers. Later on in life, I realized that you could do it with just your fingers. The springs aren't actually that strong (or maybe I just have strong fingers).
In any case, I stopped using tools of any kind to remove and re-install the anti-rattle springs on my stock brakes. Much easier on the paint.
In answer to the question on wear sensors and AP Racing brake pads, "no" they don't accomodate the sensor. You just zapstrap the wire out of the way and check them once in a while.
