Frenkit Performance Rear Brake Caliper Seal Rebuild Kit - Universal - Brembo 4-Pot 28/32mm
This Frenkit Performance seal kit rebuilds one rear Brembo 4-piston caliper with 28mm and 32mm pistons, a caliper fitted to some Audi, Mercedes-AMG, Jeep and Tesla models. It replaces the pressure seals and dust boots with Frenkit's grey high-temperature silicone parts, which stay flexible through repeated heat cycles where standard rubber hardens and cracks. 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: For rear Brembo 4-pot calipers with two 28mm and two 32mm pistons; measure your pistons before ordering, as Brembo calipers vary by model. One kit services one caliper, so order two for a pair. Installation by a professional is recommended.
