Dorman - First Stop Brake Master Cylinder P/N:M390344

Turn brake-pedal effort into the hydraulic pressure that operates your brakes with the Dorman – First Stop Brake Master Cylinder (M390344). It drops in as a direct-fit replacement for the 1996-1997 Nissan Pickup [All], engineered to replicate the original master cylinder's design and function on that application.

• 100% new: built entirely from new materials — not remanufactured.
• Aluminum housing: the cylinder housing is 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.
• Spec'd to fit: 1-inch bore, three outlets, and M10 x 1.0 outlet threads; includes the reservoir and the sensor. Made to meet SAE International standards.

The master cylinder converts the force from your brake pedal into hydraulic pressure and distributes brake fluid to the brake circuits. If a failing master cylinder is the cause, signs it may need replacing include a brake pedal that slowly sinks under steady foot pressure, a spongy pedal, or unexplained fluid loss — diagnose the cause before replacing. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
