Technical Details and Construction

This Dorman brake hydraulic hose (part number H621239) is designed as a flexible hose with an EPDM rubber core, known for its resistance to heat, ozone, and brake fluid degradation.

The fittings have a thread diameter of 10 mm (M10 x 1.0), matching OEM specifications for the Audi Huracan and Lamborghini R8.

Applications and Problem Resolution

This brake hydraulic hose is intended for use in the brake system of compatible vehicles, facilitating the transfer of brake fluid from the master cylinder to the brake calipers. It addresses several common issues:

• Replacement of worn or cracked brake hoses causing fluid leaks
• Restoring proper brake fluid pressure and pedal feel
• Preventing hose swelling or bursting under high pressure
• Eliminating brake drag caused by damaged or collapsed hoses
• Ensuring safe and reliable braking performance on Audi Huracan and Lamborghini R8

Installation Notes and Tips

When installing the Dorman H621239 brake hydraulic hose, ensure the vehicle is securely lifted and supported. Carefully remove the old hose, avoiding contamination of the brake fluid system. Verify that the male and female fittings align correctly with the brake lines and calipers. Since mounting hardware and brackets are not included, reuse existing components or source OEM parts as needed. After installation, bleed the brake system thoroughly to remove air and restore proper brake function.
