If you're rebuilding or servicing your StopTech ST-22, ST-40, ST-45, ST-60, or ST-65 brake calipers, a fresh dust boot is essential for keeping dirt and road debris out of the caliper piston bore. This is the specific 34mm dust boot designed to fit those StopTech caliper models, ensuring a proper seal and protecting the internal components from contamination.

Keeping the caliper piston area clean is crucial for consistent brake performance and to prevent premature wear or sticking. This replacement boot is made to the same specifications as the original, so it fits right and does its job of keeping contaminants away from the piston and seal. It's a small part, but it plays a big role in the overall health of your braking system.
