08 SD brake caliper bolt

Hello guys,

I was trying to figure it out the rear brake caliper + pads and I did something unnecessary stupid due to curiosity.

I managed to take the rubber out of a bold that holds the caliper to the bike and I have no clue how to put it back. Also, it seems like i can be ok without the rubber. See pic and let me know what to do.

Disregard the numbers in pic





Thanks

Not ok without the rubber, it corrodes up and I believe there is also some play.
Take it apart and push the rubber back in and then reassemble the lot.
It's a while ago I had this apart but from memory you can't push the rubber in with the pin still inside the hole.

Ok Thank you. Now its just figuring out how to take it apart =). Any suggestions would be great.

Thanks
