Titanium caliper piston. Titanium Nitride coated. Part: 43048-1078 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. Half the weight of the original part. These pistons reduce Unsprung weight, giving your suspension a quicker reaction time to bumps 27mm diameter piston (approximate size as I don’t want rival companies knowing the true dimensions) 22.5mm deep This part was made as a performance upgrade to the original steel part which corrodes and damages the seals causing the caliper to leak. 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 Weight = 30gm The OEM part is £27.32 to buy from a major dealer, so this Titanium upgrade is a bargain! This part does NOT come with seals THESE PISTONS ARE NOT POLISHED
