Keep hydraulic pressure flowing to the front brakes with the Sunsong brake hose, part number 2205396. This front brake hydraulic hose is a direct-fit replacement for the 2011-2017 BMW X3 and the 2015-2018 BMW X4. See the Buyer's Guide tab for engine-specific details.
A brake hose is the flexible link between the rigid brake lines and the caliper. It carries pressurized brake fluid while letting the wheel steer and the suspension travel. Sunsong is a vertically integrated maker of automotive fluid transfer hoses and lines, and it develops its hoses around what installers need, with exact form, fit, and function.
A brake hose may need replacing if you notice a soft or spongy pedal, fluid seeping at the hose or its fittings, or cracking, swelling, or chafing on the outer cover. Have the brake system inspected to confirm the cause. After installation, bleed the brakes as described in the vehicle service information.
