Raybestos MC390849 Element3 New Brake Master Cylinder

The Raybestos MC390849 is a brand-new Element3 brake master cylinder engineered to meet or exceed original equipment specifications. As the heart of the hydraulic brake system, the master cylinder converts brake pedal input into hydraulic pressure, delivering consistent and reliable stopping force. This unit features a single-bore-dual hydraulic channel design and is built to perform exactly like the factory part it replaces.

Key Features:

• OE-Matched Bore Size and Finish: Prevents fluid bypass that can cause loss of hydraulic pressure and extends service life
• New Piston Assembly and Return Spring: Prevents brake drag that can overheat calipers and rotors, increasing pad life
• EPDM and SBR Rubber Components: Meet SAE specifications and are compatible with brake fluid; resist heat, corrosion, and leakage
• Hardened Zinc Dichromate Bleeder Screws: Trivalent coating provides extra protection and added durability
• Precision Cast Housing: Manufactured from precision castings for an exact OE fit; reduced-weight design that does not stress the brake booster mounting
• 100% New Construction: Not remanufactured — every component is new for reliable, consistent performance
