Durable Construction and Design Features

This Dorman brake hydraulic hose (part number H380479) 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 of the hose are equipped with treated steel fittings—one banjo fitting with a 10 mm thread diameter and one female fitting with an M10 x 1.0 inside diameter—ensuring a secure connection to your vehicle's brake system. The included gaskets help maintain a tight seal, reducing the risk of leaks.

Applications and Problem Resolution

This brake hydraulic hose is specifically designed for use in the brake systems of Buick Cutlass Supreme and Oldsmobile Regal vehicles. It addresses common brake hose issues such as:

• Cracked or worn flexible brake hoses causing fluid leaks
• Swollen or deteriorated hose material reducing braking efficiency
• Corroded or damaged steel fittings compromising brake fluid flow
• Brake fluid contamination due to compromised hose integrity
• Incorrect hose length or fitting type leading to improper installation

Installation Notes and Tips

When installing the Dorman H380479 brake hydraulic hose, ensure the vehicle is safely supported and the brake system is depressurized. Use the included gaskets to achieve a proper seal at both fittings. Verify that the banjo and female fittings align correctly with the brake caliper and hard line connections. After installation, bleed the brake system thoroughly to remove any air and restore optimal brake performance.
