• Reduced braking response during normal driving
• Brake system performance issues on front disc brake vehicles

Installation Notes

• Verify vehicle fitment by year, make, model, and front disc brake configuration before installation.
• Bench bleed the master cylinder before connecting brake lines to reduce trapped air in the hydraulic system.
• Use clean DOT 3 or DOT 4 brake fluid only.
• Transfer or source any required mounting hardware separately, as mounting hardware is not included.
