Convert brake-pedal force into hydraulic pressure for the front and rear circuits with the Dorman - First Stop Brake Master Cylinder M390249. It drops in on the 1994-1996 Chevrolet Caprice, the 1995-1996 Buick Roadmaster, and the 1995-1996 Cadillac Fleetwood (All engines), engineered to reproduce the design, function, and performance of the original master cylinder on those applications.

  • Aluminum housing: the cylinder housing is cast to match the casting material of the original part for similar performance.
  • Two outlets: a rearward M11 x 1.5 port and a secondary M12 x 1.0 threaded outlet (primary outlet thread pitch 1 mm), with a 1.125 in (40 mm) bore.
  • EPDM seals: 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 SAE International standards.

The reservoir is included; a sensor is not. Mounting hardware is not included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
