I have a 1.6 petrol RCZ 2013 which had new front discs and pads when I bought it, from day 1 it had brake pad rattle, if you lightly touch the brake pedal it goes away. i notice that there is no anti rattle shims where the ears of the pads run in the calliper housing’s whereas it looks like there are on the rear brake pads. can anyone tell me if this is normal or should there be a set of anti rattle shims on the front as I’m sure this would cure it.
