well, i couldnt tell you regards an actual measurement, but when you put the pads in, if you have to lift them up to get the pins through, thats wrong
obviously if using split pins with retainer plates, the plates actually keep the pads pushed all the way down, whereas pins and springs keep the pads in the same position all the time
they shouldnt rattle side to side at all so i can only assume either
pads are wrong width
calipers are worn
pads are too far up
