Dorman - First Stop Brake Master Cylinder P/N:M630615
Dorman M630935 brake master cylinder for the 2001-2005 Audi Allroad Quattro and other vehicles turns pedal force into hydraulic pressure for the brakes.
A soft or sinking brake pedal, or brake fluid around the cylinder, can mean the internal seals are leaking. If that is the cause, this Dorman master cylinder replaces the worn unit. These signs alone do not prove the cylinder is at fault, since a leaking brake line or caliper can also give a soft pedal.
It fits the 2001-2005 Audi Allroad Quattro, the 2000-2003 Audi A8 Quattro and the 2001-2003 Audi S8. Plan on one per car.
