Product Details

MPA Electrical NM3039 is engineered to restore braking performance by matching OE specifications through testing against original equipment samples and controlled validation processes. The design includes the reservoir, cap, and seal, while omitting the brake booster, push rod, sensor, pressure switch, and mounting hardware. For Chrysler Voyager, Dodge Caravan, and Plymouth Grand Voyager applications, this master cylinder supports reliable hydraulic pressure delivery in vehicles equipped with front disc brakes.

Common Brake Issues It May Address

  • Low or spongy brake pedal feel
  • Internal master cylinder leakage
  • Brake fluid loss at the master cylinder
  • Uneven or inconsistent hydraulic pressure
  • Brake warning symptoms tied to master cylinder wear

Installation Notes

Verify vehicle brake configuration before ordering, since this part is listed for front disc brake applications only. Bench bleed the master cylinder before installation, use clean DOT 3 brake fluid, and inspect brake lines and fittings for contamination or wear. Because mounting hardware is not included, reuse or source the required hardware as needed for the vehicle.

Quality Assurance

MPA Electrical validates each unit against OE specifications using proprietary testing protocols and an OE sample library to help ensure consistent brake performance out of the box. This part number is NM3039.
