Verify vehicle fitment by year, make, model, and brake configuration before installation. Bench bleed the master cylinder before connecting brake lines, then bleed the full brake system after installation to remove trapped air. Use only DOT 3 or DOT 4 brake fluid as specified, and inspect the booster, lines, and fittings for wear or contamination during service. Mounting hardware, brake booster, push rod, sensor, and brake pressure switch are not included.
