I've been using this for years now. It works great on all steel brake caliper pins. Repeat, all steel slide pins.
I was refreshing my sons brakes this past weekend. His car has the one pin with the rubber bushing. ( for vibration I believe.) I had to use a pair of pliers and use a lot of force to get the pin out. ( Same on the other side as well.) The rubber bushings had expanded. I know the manufacture says it is safe for rubber , but I'm not alone in saying otherwise. I'll be switching to something else.
