Convert brake-pedal effort into the hydraulic pressure that operates the brakes with the Dorman - First Stop Brake Master Cylinder M630210. It installs as a direct-fit replacement engineered to match the original master cylinder's design and function on the 1996-1997 Volvo 850 and the 1998-1999 Volvo C70, S70, and V70 (all engines).
The master cylinder pressurizes brake fluid to the wheel circuits each time you press the pedal. A brake pedal that sinks slowly, feels spongy, or drops toward the floor can be a sign the master cylinder may need replacing — if a failed master cylinder is the cause, this unit replaces it. This listing includes the master cylinder only; the reservoir, sensor, and mounting hardware are not included. Consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: United States.
