A used OEM Audi Brake Master Cylinder, part number 80A611021B, also supersedes the earlier 80A611021. This hydraulic component converts pedal force into the pressure needed to engage the brakes on Audi Q5, Q5 PHEV, Q5 Sportback, and SQ5 models with 2.0L four-cylinder or 3.0L V6 turbocharged gas engines. A failing master cylinder often causes a soft or sinking pedal, or a brake warning light, as internal seals degrade and allow fluid bypass.
