What It Helps Fix

• Low or inconsistent brake pedal feel
• Internal master cylinder leakage
• Brake fluid loss at the master cylinder
• Delayed hydraulic response during braking
• Brake performance issues on front disc brake systems

Installation Notes and Tips

Before installation, confirm the vehicle is one of the listed Dodge or Mitsubishi applications and verify the bore size, mounting pattern, and brake fluid type. Bench bleed the master cylinder before connecting brake lines, then bleed the full hydraulic system after installation to remove trapped air. Inspect the brake booster, lines, and wheel cylinders or calipers for wear or leaks so the new master cylinder is not affected by another hydraulic fault.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict protocols. NM52403 is a new standard replacement part built to restore braking performance for the listed Dodge Colt, Ram 50, Raider, and Mitsubishi Cordia, Galant, Mighty Max, Montero, and Tredia applications.
