Pin type caliper anti rattle springs

I know there are two deals that go on the pins [like between the pin head and the caliper itself] {keeping the caliper tight against the rotor I assume} and the wire [it needs to be installed correctly. I dont know why they would cost that much. If you could find a set of pins, would they not come with them? Other than that, dont know what to tell you. You got to have good pins and make sure the front bearings are tight. If the bearings have any play they will cause the pads to spread and the clearance will could cause rattling. Im surprised the calipers did not come with the hardware. Good luck. {might try to reduce the clearance between the pin and the pads but I do not know the best way to go about this}.
