Dorman - First Stop Brake Master Cylinder P/N:M134437

Turn brake-pedal effort into the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder (M134437). This 100% new master cylinder is a direct-fit replacement for the 1999-2004 Dodge Dakota, 1999-2001 Dodge Durango, and the 2003-2006 and 2008-2009 Dodge Viper (All engines) — see the Buyer's Guide tab for the full application list. Dorman precision-engineers it to reproduce the design, function, and performance of the original master cylinder on these applications.

• Aluminum housing: built to match the casting material of the original part for similar performance.
• EPDM rubber components: made from a high-quality EPDM compound for resistance to glycol-based brake fluid.
• Two outlets: 1.125-inch bore; rearward outlet M10 x 1.0 and secondary outlet thread M12 x 1.0, with a 1 mm primary outlet thread pitch.
• 100% new: made entirely of new materials, not remanufactured, and made to meet rigorous SAE International standards.

The reservoir and sensor are included; package contents are the master cylinder. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is the cause of a sinking pedal, fluid leak, or spongy brakes, this replaces it. Country of origin: China.
