Product Details and Specifications

The Dorman H66856 brake hydraulic hose features a black rubber outer sleeve that protects the EPDM rubber hose core from environmental damage and wear. Both ends are equipped with treated steel fittings—one male with a 7/16 in-20 thread diameter and one female with a 7/16 in-24 inside diameter—ensuring secure connections within the brake system. This flexible hose measures 13.44 inches in overall length, making it suitable for direct replacement on compatible Cadillac models. The hose does not include mounting hardware, brackets, or seals, so these components must be reused or sourced separately during installation.

Installation Notes and Tips

When installing the Dorman H66856 brake hydraulic hose, ensure the brake system is fully depressurized and the vehicle is securely supported. Inspect existing fittings and hardware for wear or damage and replace as necessary.

Since mounting hardware and brackets are not included, retain original components or acquire replacements to secure the hose properly.
