Frenkit Performance High Temperature Brake Caliper Dust Boot Kit - Universal - 28mm to 46mm
These Frenkit Performance dust boots replace cracked or melted piston boots without a full caliper rebuild. Each kit has two silicone dust boots for one piston size, and sizes run from 28mm to 46mm in 2mm steps.
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: Choose the size that matches your piston diameter. Each kit contains two boots of one size; order enough for every piston of that size. Silicone boots must be fitted dry, as grease damages them. Installation by a professional is recommended.
