Dorman - First Stop Brake Master Cylinder P/N:M390118
$128.99
The Dorman - First Stop Brake Master Cylinder M390118 converts brake-pedal force into the hydraulic pressure that operates the brake circuits, and it drops in as a direct-fit replacement for the 1992-1994 Nissan D21 [All] and the 1995 Nissan Pickup [All]. It is precision-built to reproduce the original master cylinder's design, function, and performance on the listed applications.
- Aluminum housing: the cylinder housing is constructed to match the casting material of the original part for similar performance.
- Durable EPDM rubber: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials — not remanufactured — and built to meet rigorous SAE International standards.
- Ready to install: the brake fluid reservoir and sensor are included; features three outlets, a 1 in bore diameter, and M10 x 1.0 secondary and rearward outlet threads.
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 or lost brake pressure, this unit replaces it; diagnose the cause before replacing. Country of origin: Taiwan.
