Titanium caliper piston. Titanium Nitride coated. Part: 5UN-W0057-50-00
Rear brake piston
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.
25mm x 31mm
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
As you can see from the photos the Titanium piston is 20gm lighter than the original part
The OEM part is £33.30 to buy from a major dealer, so this Titanium upgrade is a bargain!
This part does NOT come with seals
