Route pressurized brake fluid from the hard line to the caliper with the Dorman - First Stop Brake Hydraulic Hose H97664. This flexible hose flexes with steering and suspension movement while carrying hydraulic pressure to the front brake, and it's engineered to match the original hose's fit, function and performance for the front-left or front-right position. It drops in as a direct-fit replacement for the 1977-1978 Buick Electra, Estate Wagon, LeSabre and Riviera, Cadillac Commercial Chassis, DeVille and Fleetwood, Chevrolet Caprice and Impala, Oldsmobile 98, Custom Cruiser and Delta 88, and Pontiac Bonneville, Catalina and Grand Safari (All engines) — see the Buyer's Guide tab for the full list.
Signs this hose may need replacing include cracking, bulging, or fluid seepage at the fittings, or a soft, spongy pedal — if a failing hose is the cause, this replaces it. Ships as one brake hose with gaskets; mounting hardware and a bracket are not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Sold individually; order two to replace both front hoses as a matched pair. Country of origin: China.
