caliper pins

[erocka1982]

i am by no means an expert but i like to think im pretty mechanically inclined. ive been workin on cars for like 15 years but i have a pretty stupid question. on my 04 ranger, for each side, it takes two different caliper slider pins. one pin has a little rubber sleeve on it and the other one has a couple grooves in it.and no rubber sleeve. i dont get it. they seem to fit just fine either way i install them.i would imagine theyre designed that way for a reason????

The best answer I can give is...just cuz.

I've seen them with one with a rubber piece and one with out, and also some with both that are without.
