hi there hope somone can help just bought some genuine brake pads these have some type of anti vibration backing material on them whichthe original pads did not have . what they had on the original pads were 2 thin metal plates on the piston side pad and 1 plate on the carrier side pad do these plates which clip on the back of the pads need fitting to the new pads as the new pads did not come with them.
