ATE Brake Pad Pins
« on: October 16, 2013, 12:52:51 PM »
I'm just in the process of replacing the front pads on my '79 R65.  While cleaning things up after I took the caliper off I notices that one of the pad pin sleeves will turn around the pin and the other does not.  Does anyone know if it is necessary for these sleeves to turn around the pins?  Or do I just grease the outside of the pin sleeve with brake grease?

Clean them do not grease them. The old ATE pin I have revolve quite freely on the spring. Keep grease away from brakes. You do not know where it will end...

I always assumed they should be free to rotate as compression of the ring is what retains the pin in the caliper.

I have to admit I very lightly coat the pins with copper grease purely for corrosion protection so that they will come out when needed at the next pad change which will likely be many years off. They have never come out so easily that it caused me any concern about their security.

They do not need to rotate as they exist solely to provide "tension" to retain the pin in place. Use the grease sparingly, as others have said, you do not want lubricants on your pads, although to be honest, a small amount would burn off relatively quickly.

It's unlikely that grease would make it's way from the pin to the pad, and even if it did, it wouldn't contaminate the whole thing at once.

A little bit of grease on the pins is fine.  Heck, it's mandatory to grease the guide bolts on floating calipers!  I like Barry's idea of using anti-seize on them.

It should just be a few gentle taps to get them in and out.  It will get easier as the compression rings get tired.  Don't worry too much about them falling out. The anti-rattle springs provide plenty of lateral force to the guide pins, and the plastic caliper cover helps hold them captive.

Thanks for the inputs guys.  I have greased them so time will tell if there is an issue with the one pin that wont rotate in the sleeve.  By the way, I always grease the pins on this bike and other bikes and cars.  I haven't had any problems with the brakes because of grease.  I use a small amount.
