No, the pad retaining pin is something different - it's only function is to hold the pads in place.
The sliding pins are the two in the diagram below shaded yellow. The two rubber boots circled red are what keeps dust, dirt and moisture out and stops them corroding. Often the boots perish and cause the sliding pins to corrode and get sticky. It is these sliding pins that need cleaning up to make sure that the two halves of the caliper can slide freely.
