Years ago I pulled off an old caliper. Cut the bottom, metal pipe near its’ base and tossed it in a parts bin. A few months ago, decided I needed that one rebuilt. I unscrewed the bit of brake pipe and flair nut. Drilled out the pipe, then tapped the nut to a std. grease nipple. Clipped on my grease gun and the pad and seal pumped out smoothy! Wrap it in a rag to catch the bits, but never any drama! Much safer than comp. air........
