Frenkit Performance Brake Caliper Piston & Seal Rebuild Kit - Nissan Skyline GT-R (R33/R34) / 350Z Track (Z33) - Front Brembo 4-Pot 38/44mm
This Frenkit Performance kit rebuilds one front Brembo 4-pot caliper with 38mm and 44mm pistons, as fitted to the Nissan Skyline GT-R (R33/R34) and 350Z Track (Z33). It includes a full set of new OE-specification pistons, so it suits calipers with pitted or corroded pistons as well as tired seals.
Frenkit Performance kits use grey high-temperature silicone dust boots and bleeder caps that stay flexible through repeated heat cycles, where standard rubber can harden and crack. Frenkit rates the silicone for continuous use from -60°C to +200°C, and each kit includes a caliper temperature sticker so you can see how hot the caliper has run.
Note: This kit services one caliper; order two for a pair. Suits the Brembo front caliper only; confirm your car has the Brembo brakes before ordering. Installation by a professional is recommended.
Features
- Four new pistons (2 x 38mm, 2 x 44mm) made to OE specification
- Grey high-temperature silicone dust boots and bleeder caps
- Fresh pressure seals for all four bores
- Bleed screw and caliper temperature sticker included
- Suits track days and hard road driving
