Hi all... My car is not Nissan, but I used R32 4pot Sumitomo brake caliper to my car. Few months back changed my front brake pad, the somehow this pad retainer are gone!!! Now my brake got sound like longgar...I've asked around, the brake can still work and the pad will stay there, but the sound really irritates me... I'm wondering if anyone got spare? Or know where to get it... Sorry, if this is not permitted here...admin can remove if it's not suppose to be here. Thanks.
