Frenkit Performance Brake Caliper Seal Rebuild Kit - Porsche 911 (964/996) / Boxster (986/987) / Cayman (987) - Front Brembo 36/40mm
This Frenkit Performance seal kit rebuilds one front Brembo 4-piston caliper with 36mm and 40mm pistons. It suits the Porsche 911 (964 C2 and C4, 996 Carrera and C4S), the Boxster and Boxster S (986 and 987) and the Cayman, Cayman S and Cayman R (987).
Frenkit Performance parts use a peroxide-vulcanised silicone rubber developed for high brake temperatures. It works from -60°C to +200°C continuously and copes with short spikes to 300°C, and Frenkit says it keeps its properties about 30% better than rival materials after 70 hours at 200°C.
Note: One kit covers both piston sizes in the caliper (two 36mm and two 40mm). It replaces Brembo rebuild kits 105.5955.56 (36mm) and 105.5955.58 (40mm). One kit services one caliper; order two kits for a pair. Installation by a professional is recommended.
