Installation Notes and Tips
Verify vehicle fitment by year, make, model, and front disc brake configuration before installation. Mounting hardware, push rod, brake booster, sensor, and brake pressure switch are not included. Bench bleed the master cylinder before installation, then bleed the brake system thoroughly with DOT 3 fluid to remove trapped air and restore pedal firmness.
