Generate the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M390044, which converts the force you apply at the brake pedal into the hydraulic pressure that operates the braking system. It installs as a direct-fit replacement for the 1992-1995 Honda Civic [All] and the 1995-1997 Honda Civic Del Sol [All].
- Aluminum housing: Precision-engineered and built to match the casting material of the original part for comparable performance.
- Fluid-resistant seals: Rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: Made entirely of new materials — not remanufactured.
- Built to spec: Made to meet SAE International standards.
This unit has two outlets and a 0.938 in bore, with a rearward outlet of M12 x 1.0 and a secondary outlet thread of M10 x 1.0. 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: Taiwan. If a failing master cylinder is the cause, signs may include a brake pedal that slowly sinks to the floor, a spongy pedal, or loss of hydraulic pressure.
