Detailed Description

This brake master cylinder is built for Chrysler Town & Country, Chrysler Voyager, Dodge Caravan, and Dodge Grand Caravan models equipped with front disc brakes. Part NM3039A is a direct hydraulic replacement that helps restore brake pedal feel and system pressure by replacing a worn or leaking master cylinder with a new aluminum unit. The reservoir is included, along with the cap and seal, while mounting hardware, push rod, brake booster, sensor, and brake pressure switch are not included.

This part cross-references Monroe Shocks & Struts (e.g., 4683) for the same application.

What It Helps Fix

  • Low or spongy brake pedal feel
  • Brake fluid leakage at the master cylinder
  • Uneven hydraulic pressure in the brake system
  • Delayed or inconsistent brake response
  • Wear-related loss of braking performance on front disc brake vehicles

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front disc brake configuration before installation. Bench bleed the master cylinder before connecting brake lines, then fill with DOT 3 brake fluid and bleed the system thoroughly after installation. Inspect the brake booster, lines, and fittings for wear or contamination before returning the vehicle to service.

Quality Assurance

MPA Electrical brake master cylinders are tested against OE specifications using proprietary processes and strict protocols to help ensure consistent braking performance out of the box. Part NM3039A is a new standard replacement built for the listed Chrysler and Dodge applications.
