Open-end wrenches should be used on the hose ends and they should not be bent, twisted, or strained.

To replace the flexible hose, clean all dirt away from the hose and line fittings. Using a flare-nut wrench, disconnect the metal brake line from the hose fitting and plug the metal line to prevent leakage and contamination. Remove the brake hose bracket/fitting assembly by removing the mounting bolt. Unscrew the banjo bolt at the caliper and remove the hose, discarding the sealing washers. Attach the new brake hose to the caliper using new sealing washers and tighten the banjo bolt. Attach the brake hose bracket/fitting assembly to the vehicle, ensuring the hose isn't kinked or twisted. Connect the metal line to the hose fitting, tightening securely.

When the vehicle is raised and securely supported on jackstands, inspect the rubber hoses that connect the steel brake lines to the front and rear brake assemblies for cracks, chafing of the outer cover, leaks, blisters, and other damage. Use a light and mirror for a thorough check.
