Nugeon 99-00820A front left brake caliper for the 2003-2005 Hyundai Sonata and other vehicles squeezes the pads against the rotor to slow the wheel. This Nugeon brake caliper is remanufactured and uses brake fluid pressure from the pedal to move its piston.
Pulling to one side under braking, fluid at the piston boot or one pad wearing faster than the other can mean a disc brake caliper is failing. Pads and hoses can also be behind those symptoms, so look at the boot and the pad wear during a brake service, engine off and cool, before replacing anything. Calipers are normally replaced as a pair across the axle, and this listing is one front left caliper.
The 2003-2005 Hyundai Sonata, the 2003-2006 Kia Optima and the 2005-2006 Kia Magentis take this caliper, along with more vehicles. The 2003-2005 Hyundai Sonata takes one on the front left, and the front right is ordered separately. If your car isn't named here, check its years and engine in the "Vehicles it fits" section.

No, brake pads, anti-squeal shims, wear sensors and bracket mounting bolts are not included; the caliper comes with its bracket, slides, dust boots and hardware.
What size piston does this front left caliper have?
Nugeon 99-00820A has one steel piston, 57 mm (2.24 in) across, in a floating design with a banjo bolt inlet (M10 - 1.0 thread).
Can a sticking caliper make a car pull to one side?
Yes, a sticking caliper can be one cause, though worn pads or a brake hose problem can pull a car to one side too. Fluid at the piston boot and uneven pad wear are other signs, and a shop can find the cause.
