Just got new caliper bolts/pins and also got a hardware kit to replace the sleeves. I know what most of the parts are for but their are 3 little o-rings, maybe should have been 4, but anyways I have no idea what they are for. I took a picture so if anyone has used a hardware kit before please let me know what the smaller o-rings are for.

What is this for??

 

They go on the unthreaded end of caliper bracket. Your pin is threadead near the head and the bottom of the shaft is not threaded. This smaller o ring is used for keeping that loose end in place and prevent it from rocking when torsion is aplied to the caliper.

I believe an exploded view of the caliper bracket in any service manual will show this.

 

My question was not directed at the items in the photo, but the vehicle being discussed. Basic information that is required to make sure that all information given is accurate.

 

the last caliper and pins i replaced did NOT have any o-rings
91 4wd

Point taken.

 

it is a 94 s10 4.3 4x4 engine w. I ended up using the existing big orings for the pins because I couldn't get the new rings in and be able to push the pins through. drove to colorado from mn and had no problems with my brakes so i'm guessing you only need the big oring if you can get the pins through them and the new sleves and lots of brake grease. I couldn't find any use for the smaller orings so hopefully they are not needed on my truck.
