Mustang Dual Bowl Master Cylinder For Manual Disc/Disc or Disc/Drum Brakes 1965-1973
Part Number: MC11378M
Dual bowl brake master cylinder for 1965-1973 Mustangs with non-power disc/disc or disc/drum brakes.
The single master cylinder that the 1965-1966 Mustang is originally equipped with provides fluid pressure to all four wheels at the same time. All four wheels are linked together in a hydraulic fluid circuit. If a problem develops in any of the four brakes, lines, hoses or single master cylinder, that creates a fluid pressure loss. This will cause you to lose both front and rear brakes.
With a dual master cylinder, the brakes are split front and rear. If a problem develops in the front, only the front brakes would be lost. You would still have the rear brakes to bring you to a stop. The same would happen if you had a problem with the rear brakes, you would still have the front brakes to bring you to a stop.
This master cylinder has a 1" bore and will fit disc/drum and disc/disc applications. The front outlet is 3/8"-24 and the rear outlet is 1/2"-20.
Dual bowl conversion lines are required for installation on a 1965-1966 Mustang.
