Turn brake-pedal effort into the hydraulic pressure that operates your brakes with the Dorman – First Stop Brake Master Cylinder M390328. It drops in as a direct-fit replacement for the 1996-2000 Honda Civic [All], where the master cylinder pushes fluid through the brake circuits each time you press the pedal. If a leaking or internally bypassing master cylinder is the cause of a sinking pedal or reduced braking, this replaces it. Dorman engineers this unit to match the original's design, function, and performance on the listed application.

  • 100% new: made entirely of new materials, not remanufactured.
  • Aluminum housing: constructed to match the casting material of the original part for similar performance.
  • Durable EPDM rubber: all rubber components resist glycol-based brake fluid.
  • Dual outlets: two outlets with a 0.813 in bore and M10 x 1.0 outlet threads (1 mm pitch).
  • Made to meet SAE International standards.

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