Factory disc brakes on my 66 Valiant

Hi all , Been a little while since I've been on here. So here's what I'm trying to find out. My brake pads in my factory disc brakes rattle around in the caliper. This doesn't seem to me that this is normal. The brakes work just fine but the noise is getting irritating. They are four piston caliper brakes. They load right in to the top of the caliper. Pads look fine. Both sides are the same way. It seems to me some kind of spring clip of some sort should be there so they don't rattle. Been trying to find this damn noise for over a year now. Forgot to take pics. The car is on the lift at my buddies. Any info would be very helpful. Thanks in advance.


Shoe Retainer Clips in place? Could be loose
