Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front disc brake configuration before installation. This master cylinder does not include mounting hardware, a push rod, a brake booster, or seals/gaskets. Bench bleeding is recommended before installation, and the system should be filled with DOT 3 brake fluid only. Confirm the reservoir and cap are properly seated, then bleed the brake system according to the vehicle service procedure.
