It is the flexible section that carries brake fluid to the brake at the wheel while moving with the suspension and steering. It fits many vehicles, among them the 2002-2007 Lexus SC430, 1998-2005 Lexus GS300 and 2001-2005 Lexus GS430. It is cataloged for the front left and front right positions and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
Brake hoses flex constantly and face road spray, heat and debris, so over time they can crack, bulge or seep fluid. After installation, bleed the brake system. Consult the vehicle service information for the correct fasteners, sealing washers and torque values, and for whether the originals may be reused.
