If it frees up after warming them then you'll know that they are probably working normally. Have you tried spraying Brake Cleaner in those "small, greasy, dark holes" and then twisting a rag or paper towel around inside to clean it out?Thanks, XFiber.
I use a shop rag to clean them off. It appears I'm cleaning off the grease I just put in. I really don't put much effort into cleaning them. Maybe that's my problem.
Good question about the temperature. I've never needed to use heat. The force required to get them out is not ridiculous - just way more than a slide pin should need. Maybe I'll throw some heat on the carrier at the next inspection and see if they free right up.
I have never looked inside the carrier. I will attempt next time, but I assume it's going to be a small, greasy, dark hole.
I appreciate your thoughts.
If the rubber dust boots are swelling, don't you think they would be loose instead of binding?Even though the Permatex purple claims to be safe for rubber parts, there are reports (on the internet) of it causing swelling on certain rubber components. Maybe the Permatex is swelling the rubber sleeves on the slide pins.
Have you considered trying Lithium Grease?Please note that even though I do use the purple Permatex on the brake pad clips and the back of the brake pads, I have always used Sil-Glyd brake lubricant on the slide pins, so I don't have any personal experience with the Permatex on the slide pins.
Well, that was news to me!! The only parts I found didn't show the pin on the left. Although some rebuild kits did have the rubber sleeves in them. Sil-Glyd would be a better product for that application as the lithium grease will interact with the rubber.Not the dust boots, I'm talking about the rubber sleeve on the slide pins:

Sil-Glyd has always worked well for me, is there a reason I should switch to Lithium Grease?
