Product Details

The DFC Brake Master Cylinder is part of Dynamite Friction’s brake hydraulics lineup and is built for the listed Chrysler applications. The 1 1/8-inch bore size is an important specification for brake system matching, while the no-reservoir configuration lets you retain the existing reservoir when the original unit is serviceable. If you are replacing a worn Chrysler Pacifica brake master cylinder or sourcing a Chrysler Voyager master cylinder replacement, 355-40046 provides the correct fitment for the vehicles shown.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Soft or inconsistent brake pedal feel
• Internal master cylinder leakage
• Brake fluid bypass within the hydraulic circuit
• Loss of hydraulic pressure at the brake pedal
• Replacement needs on high-mileage Chrysler Pacifica, Grand Caravan, or Voyager models

Installation Notes and Tips

Verify bore size and reservoir transfer requirements before installation. Bleed the brake system thoroughly after replacement to remove trapped air and restore proper hydraulic operation. Confirm the vehicle application by year and model before ordering, especially for 2017-2024 Chrysler Pacifica, 2021-2022 Chrysler Grand Caravan, and 2020-2022 Chrysler Voyager applications.

Quality Assurance
