  Cylinder Assembly Master, brmc210

• Description:

  This genuine Ford brake master cylinder assembly, catalog number DR3Z-2140-A, is the hydraulic heart of the service brake system on the 2010-2014 Ford Mustang. Bolted to the brake booster, it converts brake-pedal force into hydraulic pressure, sending fluid through the primary and secondary circuits to the front and rear calipers. The assembly includes the integral fluid reservoir. A worn or leaking master cylinder produces a soft, spongy, or slowly sinking brake pedal, reduced stopping power, external fluid weeping at the booster face, or a pedal that fades toward the floor under steady pressure as the internal seals bypass. Because it feeds both brake circuits, a failing master cylinder is a critical safety concern and should be replaced promptly. This genuine Ford unit matches the original bore diameter, port configuration, and reservoir geometry for correct pedal feel and balanced system pressure. Bench-bleed the master cylinder before installation and perform a full system bleed afterward to purge all air from the lines; use only the Ford-specified brake fluid grade. Follow Ford torque specifications on the mounting nuts and brake line fittings, and replace any fasteners Ford designates as single-use rather than reusing them.
