Piston Seals & Dust Boots

Our caliper piston seals and dust boots are compatible with the calipers in all StopTech and Brembo big brake kits. Please select the seals and dust boots to match the caliper piston diameters used in your kit.

If your car came with fixed Brembo calipers from the factory, these are also compatible with almost all OEM applications as well. Notable exceptions include the Ford Focus RS (Mk3) and 2018+ Subaru WRX STI. If you have any questions, please don't hesitate to contact us for assistance.
