Dorman M390096 Brake Master Cylinder New OEM Replacement

The Dorman M390096 is a 100% new brake master cylinder engineered as a direct OEM replacement for select Ford Aerostar models. Unlike remanufactured alternatives, this unit is built entirely from new components, delivering consistent, reliable braking performance right out of the box.

The cylinder housing is cast to match the material and geometry of the original factory part, ensuring a precise fit and predictable hydraulic performance. All internal rubber components are manufactured from high-quality EPDM compound, which provides excellent resistance to glycol-based brake fluids and long-term durability under demanding braking conditions.

Key Features:

• 1.0625-inch bore diameter matched to OEM specification
• Aluminum construction for strength and corrosion resistance
• Two outlets with 3/8-24 forward and rearward outlet threads
• EPDM rubber seals formulated for glycol-based brake fluid compatibility
• 100% new — not remanufactured — for maximum quality and safety
• Manufactured to meet rigorous SAE International standards
• OEM cross-references: F29Z-2140-A, F69Z2140AA, MC390096

This master cylinder is sold as a single unit and is designed for straightforward installation using standard hand tools. California Residents: This product is subject to Proposition 65 warnings. See P65Warnings.ca.gov for details.
