  • Brake fluid leaks at the master cylinder body or reservoir area
  • Loss of hydraulic pressure in the brake system

Installation Notes and Tips

Confirm vehicle fitment by year, make, model, and front disc 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 brake fluid and inspect the brake booster, lines, and fittings for wear or leakage during service. Mounting hardware, brake booster, push rod, and brake pressure switch are not included.
