Dorman - First Stop Brake Master Cylinder P/N:M99084
Dorman M630601 brake master cylinder for the 2007-2009 Nissan Altima converts pedal force into hydraulic pressure that works the brakes.
A brake pedal that sinks toward the floor or feels soft, or fluid seen around the cylinder, can mean the master cylinder is worn. A leaking brake line or a worn caliper seal can produce similar signs, so find the cause before you replace anything. If a failed master cylinder is the cause, this one replaces it. Each car takes one.
This is a direct-fit replacement for the 2007-2009 Nissan Altima.
