What It Helps Address

• Low or inconsistent brake pedal feel
• Internal master cylinder leakage
• Brake fluid loss at the hydraulic unit
• Reduced braking response in front disc brake systems
• Wear-related failure in the original master cylinder

Installation Notes and Tips

Before installation, confirm the vehicle is equipped with front disc brakes and verify the mounting pattern, bore size, and fluid requirements. Use DOT 3 brake fluid and bleed the brake system thoroughly after installation to remove trapped air and restore proper hydraulic pressure. Inspect the brake booster, lines, and related components for wear or leakage before completing the repair.
