I'm replacing OEM Toyota pads with OEM Toyota pads, and transferring the shims and "wear clips" (cuz the OEM pads don't include them)... but the clips just don't fit right on the new OEM pads. The pads look identical, but the clips are somehow not sitting "flat" if the makes sense, and it makes them almost impossible to install without forcing them in... which I don't like. so...do I really have to use the clips? do they do more than squeak when the pads are low? I don't want to send the wife back on the road and have her brakes seize up from dragging, and I really don't want to drive back to the dealer 45mi away.
