Durable Construction and Precise Fitment

This Dorman brake hydraulic hose (part number H620790) is built with EPDM rubber, known for its resistance to heat, ozone, and brake fluid degradation. The black rubber outer sleeve adds an extra layer of protection against abrasion and environmental factors. Both ends feature treated steel fittings—one banjo type with a 10 mm thread diameter and one female fitting with an M10 x 1.0 inside diameter—ensuring a secure and leak-free connection. The included gaskets help maintain a tight seal, critical for maintaining brake system integrity.

Applications and Problem Resolution

This brake hose is specifically designed for use in the braking systems of Buick Montana, Chevrolet Uplander, and Pontiac Terraza models. It addresses common brake hydraulic hose issues such as:

• Cracked or leaking brake hoses causing fluid loss
• Swollen or deteriorated hose material reducing braking efficiency
• Corroded or damaged fittings leading to brake fluid leaks
• Incompatible hose length or fittings causing installation difficulties
• Worn seals resulting in brake system pressure loss

Installation Notes and Tips

When installing the Dorman H620790 brake hydraulic hose, ensure the vehicle is safely lifted and supported. Carefully remove the old hose and inspect the brake line fittings for damage or corrosion. Use the included gaskets to create a proper seal at the connection points. Since mounting hardware and brackets are not included, reuse the existing components if they are in good condition. After installation, bleed the brake system thoroughly to remove any air and verify there are no leaks before driving.
