play in caliper

[Stevo]

On my rear caliper the bolts are tight but it moves up and down on the slider on the swingarm? What would cause this i have a rad tapered carrier, will it hurt anything?

is the o-ring still in the caliper mount, when i didnt put mine in it somehow caused a bearing in my carrier to go bad. Atleast thats what RAD said:confused:
