Start by cleaning all dirt from the hose fittings. Use a flare-nut wrench to disconnect the metal brake line from the hose fitting, being cautious not to bend the line. If the fitting is corroded, apply penetrating oil and allow it to soak for 10 minutes before trying again. Avoid attempting to break loose a frozen fitting nut, as it could kink the metal line, requiring replacement. Disconnect the brake hose from the frame or bracket by removing the U-clip and promptly plug the metal line to prevent excessive leakage and contamination. 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 tightening the banjo bolt to the recommended torque. Place the end of the hose fitting into the frame or bracket, ensuring it follows the same route as the original one, and secure it with the U-clip. Thread the metal line to the hose and tighten the brake tube fitting nut securely. Check for any interference with suspension or steering components, making adjustments as necessary. After installation, bleed the brakes, check the master cylinder fluid level, and test the brake operation before resuming normal service.
