Dynamic Friction Company 347-00046 Disc Brake Caliper Piston Seal Kit

The Dynamic Friction Company 347-00046 is a disc brake caliper piston seal kit designed to restore proper caliper function and hydraulic integrity. Caliper piston seal kits replace the rubber seals and boots that keep brake fluid contained within the caliper and protect the piston from contamination — components that can harden, crack, or swell over time, leading to fluid leaks, uneven brake drag, or reduced stopping performance. Rebuilding a caliper with fresh seals is a cost-effective alternative to full caliper replacement when the caliper bore and piston are otherwise in serviceable condition.

This kit fits a wide range of applications spanning model years 2005–2025, with coverage across select Ford, Ram, Lincoln, Dodge, and Mitsubishi vehicles.
