Dorman - First Stop Brake Master Cylinder P/N:M630601

Turn brake-pedal effort into the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M630601, engineered to drop in like the original on the 2007-2009 Nissan Altima (All engines). The master cylinder converts the force applied at the brake pedal into hydraulic pressure that travels through the brake lines to the wheel circuits; if a leaking or worn-out original is behind a sinking or spongy pedal, this unit replaces it.

• 100% new: made entirely from new materials, not remanufactured, for consistent quality and safety.
• Aluminum housing: constructed to match the casting material of the original part for similar performance.
• Durable rubber: internal rubber components use a high-quality EPDM compound that resists glycol-based brake fluid.
• Strict specifications: made to meet rigorous SAE International standards.
