Product Features and Specifications

The Dorman H380733 brake hydraulic hose features a flexible EPDM rubber hose core that resists heat, ozone, and brake fluid degradation. The black rubber outer sleeve provides additional protection against abrasion and environmental factors. Both ends of the hose are fitted with treated steel connectors—one male and one female—to ensure secure and leak-free connections within the brake system. The hose measures 18 inches in overall length, making it suitable for a range of BMW models including the 5 Series, 7 Series, 8 Series, and M5 variants. This hose does not include mounting hardware, brackets, or gaskets, so those components must be sourced separately if needed.

Applications and Problem Resolution

• Replaces worn or cracked brake hydraulic hoses causing fluid leaks
• Restores proper brake fluid pressure and pedal feel
• Prevents brake system failure due to hose deterioration
• Addresses issues with hose swelling or bulging under pressure
• Eliminates brake fluid contamination from damaged hose outer sleeves

Installation Notes and Tips

When installing the Dorman H380733 brake hydraulic hose, ensure the vehicle is securely lifted and supported. Carefully remove the old hose, taking note of the orientation and routing. Clean the fittings and inspect for corrosion before attaching the new hose. Use appropriate tools to tighten the treated steel fittings to manufacturer torque specifications. Bleed the brake system thoroughly after installation to remove air and restore proper brake function. Since mounting hardware and brackets are not included, verify that existing components are in good condition or replace as necessary.
