Need a new brake caliper for the back right (passenger side) of your Ford Taurus (2010-2012) or Lincoln MKS (2012)? This A-Premium kit is a complete assembly. It includes the caliper itself, the mounting bracket, a steel piston (single piston, 42.8mm diameter), and all the necessary installation hardware. The inlet port for the brake line and the bleeder valve port are both M10 x 1.0 thread size. It's coated with an anti-rust finish. This is a direct replacement for OEM numbers like AG1Z2552A, AG1Z2552B, and others listed. Important: This is for the REAR RIGHT (passenger side) only. Always double-check your vehicle's year, make, model, and exact brake configuration before buying any brake part. They offer a one-year unlimited mileage warranty. Good for a DIY repair if you're comfortable with brakes, or for a mechanic to install.
