Genuine OEM Audi Rear Brake Hose, part number 7P0611776. This critical component is responsible for transferring hydraulic fluid under high pressure from the brake lines to the rear brake caliper, enabling the braking action. It is positioned at the rear wheel assembly, connecting the fixed brake line to the moving caliper. Constructed from reinforced rubber with durable metal fittings and often protected by a coiled spring, it is designed to withstand extreme pressure and constant flexing. Choosing a genuine OEM brake hose ensures the correct length, precise fittings, and high-pressure resistance, which are vital for maintaining brake system integrity and vehicle safety.
