Thanks..
Wellas I mentioned, i only found 2 clips, one on each side
Heres a photo of the clips I found..
The piston side of the old pad has a wear mark that seems to match the wear mark on the clips so I assume the clip was a spacer of sorts to take up the front to back slack of the pad in the caliper?
The brakes were ok before, stopped ok and no noise.
Are the anti rattle clips necessary
