Frenkit Brake Caliper Rebuild Kit - Subaru WRX STI (GD/GG/GR) / Mitsubishi Lancer Evo (CP9A/CT9A/CZ4A) - Front Brembo 4-Pot
This Frenkit kit rebuilds one front Brembo 4-piston caliper on the Subaru Impreza WRX STI (GD/GG and 2008-on GR hatch) and the Mitsubishi Lancer Evolution V to X GSR. It replaces all four pistons (two 40mm and two 46mm) and includes new seals, dust boots, crossover O-rings and bleed screws.
Frenkit is a Spanish brake hardware maker with around 50 years in the business. Its parts are made to meet or exceed OE specification under an ISO 9001 quality system, so a rebuild restores the caliper without the cost of a new one.
Note: Only for the factory Brembo 4-pot front caliper with 40mm and 46mm pistons. One kit services one caliper; order two kits for a pair. Installation by a professional is recommended.
