Did a search on here but couldn't find anything. What is the purpose of the little bushing (or o-ring whatever you want to call it) that goes on the lower sliding caliper bolt? What happens if you don't have those on there because I don't and it seems to work fine. Only 1 of mine had a bushing on it and the new caliper bolts didn't have the bushings. I asked the guy where I got the rotors turned and he said I didn't need them. But it seems to me like they have to serve some purpose. Otherwise, they wouldn't have put them on there. Thanks in advance.

it probably will perform OK for a little while. however, if you dont want to have to replace and regrease those slider bolts then i would get a new rubber gasket thingy ASAP.

the rubber gasket helps stop sand and junk from getting in there.

How is that? I don't understand. I think you are talking about the caliper pin boots which are attached to the caliper itself. The bushing thing I'm talking about fits in the groove towards the end of the bottom caliper pin. The bottom has the groove and bushing, the top did not. Check out the link below. There's a rubber bushing that fits in that groove. What does it do?

Here's a pic of the caliper bolt

I think it's to dampen vibration, but please don't quote me on that.

I too don't know what the purpose of the rubber bushing is. I replaced the pin with the bushing on my wife's car. Mine was rusted and all chewed up. It was chewed up too much to just sand the rust off and the rubber bushing tore when taking it out. I got it at the local Toyota dealer and it came with the rubber bushing already on it. I just brought it with me and showed it to the parts guy there and he went in back and got it for me with the bushing already on it. I would also like to know what the real purpose of the bushing is.

I guess there's no reason for it? The new brakes work great!

To prevent water and salt get into the pin to get it rusty and stuck. Also apply to dust and sand.

Hmmm....

For those keep saying the bushing is to prevent dust and sand.... Please check your service manual again!!!

The bushing slosh is refering to is located why inside the bore of the torque plate!! It is fited on close to the end of the "Caliper Sliding Pin".

Here is a picture... Notice only the pin that goes on lower bore of the torque plate have a bushing. This came off 97 Camry 5S-FE, and I know for fact that 01 Solara 5S-FE has the rubber bushing on the top pin...

Any comment, guess, suggestion is welcome. I sure would like to know why toyota puts a rubber bushing on the pin.
