Dorman - First Stop Brake Master Cylinder P/N:M630649
Dorman M630668 brake master cylinder for the 2005-2009 Kia Spectra and other vehicles turns pedal force into hydraulic pressure for the brakes. It has an aluminum housing and four outlets.
A soft or sinking brake pedal, fluid around the cylinder or a falling reservoir level can mean the master cylinder is worn, but a leak elsewhere in the brake system can give similar symptoms. With the engine off, look over the cylinder, lines and fittings for wet spots to find the source first.
This is a brake master cylinder for the 2005-2009 Kia Spectra and the 2006-2009 Kia SPECTRA5.
