Installation Notes and Tips

Confirm vehicle fitment by year, make, model, and front disc brake configuration before installation. Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic system. Inspect brake lines, fluid condition, and mounting surfaces during service, and use DOT 3 brake fluid only. Mounting hardware, push rod, brake booster, sensor, and brake pressure switch are not included.
