Dorman - First Stop Brake Master Cylinder P/N:M39403
Dorman M630410 brake master cylinder for the 2004-2009 Nissan Quest turns pedal force into hydraulic pressure for the brakes. Its two outlets carry that pressure on to the brake lines.
A soft or sinking pedal, a low reservoir level or fluid around the cylinder body can mean the master cylinder is wearing out, but other brake parts can show the same symptoms. Work out where the problem starts before replacing anything. With the engine off, look at the reservoir level and the cylinder body for wetness. If the master cylinder is the cause, this unit replaces it.
This is a direct-fit replacement for the 2004-2009 Nissan Quest.
