Description:

I have scoured the net with various keywords and nobody has actually stated what the purpose of the rubber sleeve is on the bottom of a caliper pin. Im not sure all disc brakes have it, but some do and in some cases the rubber-sleeved pin goes at the top. If it helps lubricate, why doesnt the bottom one have it? Ive also run upon people with seized pins and its because the rubber can toughen up or expand and lock in place. Wouldnt it disproportionately stiffen one pin vs the other leading to uneven braking? #bundysgarage # calipepin #discbrakes Finally, mine are a bit screwed, so I plan on making new rubber sleeves with some tubing from lowes (Ill dremel wheel the matching grooves in place). Any potential problem with that, assuming I can find the right fit? The little rubber thing maybe 5 mm thick that goes in a grove at the end of the caliper pin. A couple months ago I refurbed my front brakes and had the same question. The two packs of new pins I bought had the slots for the rubber thing on one pack, but the other had no slot. I ended up not putting any of the rubber things on. It seemed like most of the reason my calipers were seizing up was that rubber thing breaking up and getting stuck in the sliding area. So far I havent noticed a problem. It may have to do with squealing but I know these cause problems for some people as they can get very tight and greatly limit movement of the pin. Using a rubber-destructive grease will certainly come into play here. On toyota/scion vehicles, there are rubber o-ring bushings on some of the sliding pins for the calipers. On the front, only the bottom one I believe has it... On the rear, both do if I remember correctly. When I did my brakes a few months ago I had big problems with the pins seizing up in the rear. Once I got them un-stuck, cleaned, relubed, replaced the pins and bushings, etc... I noticed there was much more resistance with the bushings on (I am sure by design)... Because the calipers were all seized up, there is more resistance than normal I believe. Either way, they did slide properly after the fact but not as easily as the front ones. I removed the bushings and tested the operation without and they worked extremely well with little to no resistance at all. But I figured that bushing had to be there for a reason so I made sure to keep them in and just lubed up as much as I could with sil-glyde (the permatex purple stuff seized them shortly after the first time... Dont use that stuff with any rubber). My question is, are those bushings absolutely necessary? I plan to check/lube the brakes before winter again and want to hear some opinions on these... If they help the rear brakes function better (less resistance with the pins) should I remove them? When doing my dads Prius brakes, I noticed his rear brakes had the slot for the bushings, but with no bushings present (nobody ever serviced them before me). So I am guessing it wont cause any damage if Toyota practice this on their other vehicles. Just looking for some thoughts though... What is the function of these bushings anyway? Noise?
