GQ front brake slider?

[quick6]

Just pulled the drivers side caliper off my truck apart and found one of the slider pins has some sort of rubber sleeve on the part that sits inside the caliper. I have not seen anything like this before and there is no mention in the workshop manual, just wondering if it is supposed to be there (the slider has a recess for it but is it the right slider?) and if so where to get another? It has fallen apart and was jamming the caliper.

Thanks guys, thought it might have been some bodge repair.
