The Dorman - First Stop Brake Hydraulic Hose (MPN H621187) carries pressurized brake fluid from the vehicle's steel line to the front caliper while flexing with suspension and steering movement. It's a front hose (cataloged for the front right and front left positions) that drops in as a direct-fit replacement across a range of Mercedes-Benz GL, ML and R-Class models — including the 2006-2013 R350, 2008-2016 GL550 and 2007-2011 ML63 AMG. See the Buyer's Guide tab for the full 2006-2016 application list.
No bracket, mounting hardware, or gasket/seal is included with this hose. Signs the original may need replacing include cracking, bulging, or fluid seepage at the hose, or a soft, spongy pedal; if a failed flexible hose is the cause, this replaces it. Made in China.
