Titanium caliper piston The castellated contact edge is to allow airflow into the piston cavity as well as reducing the contact area with the pad and reducing the amount of heat going into the piston and heating the brake fluid. 32mm wide x 22mm piston Kawasaki Part number: 43048-1100 These pistons have a Titanium Nitride (TiN) coating which is harder than the metal beneath and will also reduce friction with the caliper seals. The coating also gives a beautiful gold colour. It’s a shame it’s hidden within the caliper Titanium has an excellent property in that it’s a poor conductor of heat, so it’ll keep heat away from the brake fluid ZX6-R 2003 ZX10-R 2008 -2010
