The Dorman - First Stop Brake Master Cylinder (M630214) generates the hydraulic pressure that pushes brake fluid through both circuits each time you press the pedal. It installs as a direct-fit replacement for the 2000-2001 Volvo C70, the 2000 Volvo S70, and the 2000 Volvo V70 (All engines), engineered to drop in like the original master cylinder on these applications.
Signs the original master cylinder may need replacing include a spongy brake pedal or one that slowly sinks under steady foot pressure — if a failed master cylinder is the cause, this replaces it. The reservoir, mounting hardware, and sensor are not included (package contents: master cylinder); consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: United States.
