  Description:

  Genuine OEM Nissan Brake Master Cylinder Assembly — Part # 46010-9BP1A

  Replace your leaking, contaminated, or failed brake master cylinder with the factory-correct assembly for the Nissan Frontier, Xterra, and Pathfinder. This genuine OEM Nissan master cylinder is the hydraulic pump at the heart of your braking system — converting brake pedal force into hydraulic pressure that actuates all four brake calipers and wheel cylinders. The complete assembly includes the master cylinder reservoir. Direct factory fit, correct bore diameter, correct port configuration.

  Always confirm fitment using your VIN and production date before purchasing.

  Why buy OEM? The brake master cylinder bore diameter, piston seal material, and port sizing are all critical to correct hydraulic pressure output. Aftermarket master cylinders for Nissan truck platforms frequently use incorrect bore tolerances, inferior rubber seals that swell or deteriorate prematurely, and imprecise port sizing that creates uneven front-to-rear brake bias. The genuine Nissan master cylinder is the only unit built and tested to the factory hydraulic specification for your braking system.

  Symptoms this part fixes:

  • Soft, spongy, or sinking brake pedal
  • Brake pedal slowly sinking to the floor under steady pressure
  • Brake fluid leaking at or around the master cylinder
  • Brake warning light on the instrument cluster
  • Uneven braking — one side braking harder than the other
  • Brake fluid contaminated with internal master cylinder seal debris

  ⚠️ Safety Note: The brake master cylinder is a safety-critical component. Replacement should be performed by a qualified technician. A full brake system bleed is required after installation before driving.
