The DFC rear-left upper brake hose for 2008–2009 Hummer H2 is a replacement flexible line intended for the rear-left upper position. It reconnects the chassis to the rear caliper hydraulic system on those model years, supporting consistent brake fluid flow and predictable pedal feel as part of scheduled maintenance or hose replacement.
