Detailed Product Description

The MC39402 brake master cylinder is designed specifically for Ford Mustang models requiring a 21.000 mm bore size and two-port configuration.

This master cylinder supports the critical function of converting pedal force into hydraulic pressure, essential for safe and responsive braking.

  • Loss of hydraulic pressure affecting brake responsiveness
  • Brake fluid leakage from worn or damaged master cylinder seals
  • Inconsistent brake pedal feel or travel distance
  • Failure of the original master cylinder causing brake system malfunction

Installation Notes and Tips

  • Ensure compatibility with your specific Ford Mustang model before installation
  • Bleed the brake system thoroughly after installation to remove air
  • Use proper torque specifications on mounting bolts to avoid damage
  • Inspect brake lines and fittings for wear or damage during replacement
