The DFC brake hose for 2013–2019 Buick Regal (front, left) is a replacement flexible hydraulic line that restores the connection between the chassis brake line and the front caliper. Intended as a service replacement for the specified years and position, it helps maintain hose flexibility and brake system routing where the original component has aged or failed.
