I removed one of the rear brake calipers this weekend, to change a wheel bearing and I discovered that one of the sliding pins was stuck fast. It would rotate in its slide/hole but it would not move in and out.
Obviously this is not condusive to proper brake performance, so I drifted it out (requiring quite a bit of force).
It turns out the caliper pin is one of those with a cut-out and a rubber sleeve over the bottom third. The rubber is ancient/14 years old and had expanded, which jammed the pin in the slide.
I could not refit the pin with the rubber sleeve in place, so for now I put the pin back without the sleeve. I'll have to get old of a new pin and sleeve....
But out of curiosity, what does the rubber sleeve do? I suspect it's some kind of anti-rattle device but (bearing in mind it's on the rear caliper) I have not noticed any difference using the pin without the rubber sleeve attached.
