Frenkit Rear Brake Caliper Piston & Seal Rebuild Kit - Mazda RX-7 (SA22C/FC) / 323 GT-X (BG) - Single Piston 35mm
This Frenkit kit rebuilds one rear single-piston caliper with a 35mm piston on the Mazda RX-7 (SA22C and FC) and the 323 Familia GT-X 4WD Turbo (BG). It includes a new piston along with the seal and dust boot, so it suits calipers with a pitted or seized piston as well as worn seals.
Frenkit is a Spanish brake hardware maker with around 50 years in the trade, supplying vehicle makers, aftermarket distributors and caliper remanufacturers. Its parts are built to OE specification under an ISO 9001 quality system.
The seal-only version is Frenkit 235013 (replaces Mazda B6Y82646Z).
Note: This kit services one caliper; order two for a pair. Confirm your rear caliper has a 35mm piston before ordering. Installation by a professional is recommended.
