Piston for caliper - stainless steel 2 3/8'' dia

Made from stainless steel these pistons have very low thermal conductivity and an excellent corrosion resistance. In addition they are machined with cut outs to reduce surface area and heat transfer. This also allows air to pass between piston and pad for extra cooling. They are lightly waisted internally to reduce weight and have an overall depth of 33mm. These are the best pistons available.
