I just decided to clean rods that the calipers slide on, pulled the rubber grommets out and cleaned them too. Slapped it back together and we'll see.

I've been using this stuff on disk brakes for a while. A little on the back of the pads, helps with squealing, and a little on the pins and it seems to work fine. I wasn't sure about using it on this rig but I did anyway.

Thanks
