Hi

Recently changing front brake pads, I removed the front caliper pins for
cleaning and re-lubricating. When I had both pins inm y hands, I noticed thy
were both different. One was all metal, while the other had a plastic sleeve
with ridges on it.

Why are they diferent? Which one is the top pin? Does it matter if they have
been switched location top vs bottom?
