Yesterday I re-greased my caliper pins and sanded down/lubricated cast slides while inspecting steering knuckles for any signs of divots. Brake pads still look new with even wear along with the rotors and best of all no divots. I had no braking issues this was just regular maintenance and inspection. Did notice on passenger side after replacing one of the caliper pins in boot and pushing pin back and forth there was more resistance versus the other pins. Could this be a sign that the caliper is starting to go bad?
