Product Features and Specifications

This Dorman brake hydraulic hose (part number H381272) is built with an EPDM rubber hose core, known for its resistance to heat, ozone, and brake fluid degradation. The black rubber outer sleeve adds protection against abrasion and environmental factors. Both ends are equipped with treated steel fittings to resist corrosion and ensure secure connections.

Applications and Problem Resolution

This brake hydraulic hose is intended for use in the hydraulic brake system of compatible Chevrolet and GMC trucks. It addresses common issues such as:

  • Brake fluid leaks caused by cracked or worn hoses
  • Reduced brake responsiveness due to hose swelling or damage
  • Corrosion or failure of original fittings
  • Incompatibility or improper fit of aftermarket hoses

Installation Notes and Tips

Installation of the Dorman H381272 brake hydraulic hose requires proper brake system knowledge and tools. Before installation, ensure the vehicle is safely supported and the brake system is depressurized. Avoid twisting or kinking the hose during installation to maintain hose integrity. Bleed the brake system thoroughly after replacement to remove air and restore proper brake function. Note that mounting hardware and brackets are not included and should be reused or replaced as needed.
