PowerStop Disc Brake Rotor P/N:AR85178EVC
PowerStop EBR1221EVC rear brake rotor for the 2016-2019 BMW Alpina B6 xDrive Gran Coupe and other vehicles gives the brake pads a smooth, vented surface to clamp against. This PowerStop brake rotor turns the pads' clamping force into the friction that slows the wheel.
A pulsing brake pedal, grinding or deep grooves in the rotor face can mean a rotor is worn. Before you replace it, rule out sticking calipers and worn pads, since either can produce similar symptoms. Replace the rear rotors as a pair, left and right; this listing is a single rotor.
This rotor is listed for a wide range of BMW models, including the 2010-2017 BMW 550i GT xDrive and the 2010-2015 BMW 550i GT. Two rotors go on the rear axle, one per side. It is a direct bolt-on replacement, and its weight and vane count match the original equipment design. If your BMW isn't named here, find its model and years in the "Vehicles it fits" section.
