Nugeon 99-02455B rear right brake caliper for the 2017-2021 BMW 230i and other vehicles presses the pads against the rotor to slow the wheel. This remanufactured Nugeon brake caliper turns brake fluid pressure into clamping force at the rear right wheel.
A worn caliper can show up as a pull to one side, a burning smell from a wheel or a pad that wears unevenly. Because a sticking slide or a worn pad can also make a car pull or drag, look the brake over during a pad service before you replace the caliper. An axle takes one caliper on each side, and the two are normally replaced as a pair. This listing is one caliper for the rear right; the rear left is ordered separately.
The 2017-2021 BMW 230i, the 2017-2021 BMW 230i xDrive and the 2017-2020 BMW 430i are among the BMW models this caliper fits, each at the rear right. Open the Buyer's Guide tab to check your exact model and engine.
