This used OEM Porsche Brake Booster Vacuum Line with Check Valve (97035557721, also replaces 97035557720) is a genuine Porsche part removed from a donor vehicle. It serves the hybrid V6 supercharged powertrain in the Panamera, routing vacuum from the pump to the brake booster. A failing line or check valve can cause a hard brake pedal or loss of brake assist, as the system relies on vacuum for proper power-brake function.
