Installation Notes and Tips

Confirm the end fitting style, thread size, and hose length against the original part before installation. Mounting hardware, brackets, gaskets, and seals are not included, so reuse or replace those components as needed during brake service. After installation, bleed the brake system according to factory procedure and inspect all connections for leaks.
