Dorman - First Stop Brake Hydraulic Hose P/N:H620455
Keep hydraulic pressure reaching the rear brakes with the Dorman brake hydraulic hose, part number H33676, from the Dorman - First Stop line. It fits many Chevrolet and GMC vehicles, among them the 1963-1966 Chevrolet Suburban, 1963-1966 Chevrolet C10 Panel and 1963-1966 GMC Suburban. See the "Vehicles it fits" section for the full list. This flexible rear hose is precision-engineered to match the fit, function and performance of the original.
A brake hose is the flexible section of the hydraulic system. It lets fluid pressure reach the brakes while the suspension moves. Over time a hose can crack, swell or seep fluid. If a worn hose is the cause of a soft pedal or a rear brake fluid leak, this hose replaces it. Install it as part of a complete brake repair, and bleed the brake system afterward.
