Convert brake-pedal force into the hydraulic pressure that feeds both brake circuits with the Dorman - First Stop Brake Master Cylinder (M39567). It installs as a direct-fit replacement for the 1986-1990 Ford Bronco II [All] and 1986-1990 Ford Ranger [All], and is precision-engineered to match the design, function, and performance of the original master cylinder on those applications.

  • Specs: 0.938 in bore diameter, two outlets with a 7/16-24 rearward outlet size, plus an included reservoir and sensor.

Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
