$46 plus tax at the shop. 2 piston or 4 piston. Half price here so stock up. I only have 4 sets of each, new. $29ea or $25ea for all 4 sets. For the newer 4-piston calipers. Metal or semi-metallic depending on the conversation. Sometimes referred to as sintered. Much heavier bite and longevity than resin pads, and also work in the wet.
