How to inspect and replace brake hoses and Brake Line on BMW 328i?

About every six months, inspect the flexible hoses that connect the steel brake lines with the front and rear brake assemblies for cracks, chafing, leaks, blisters, and other damage. Use a light and mirror for a thorough check. If any defects are found, replace the hose with a new one. Clean dirt away from the hose ends. To remove a brake hose, unscrew the tube nut with a flare-nut wrench and remove the bolt(s) or clip(s) securing the hose to the body. Disconnect the hose from the caliper, discarding the sealing washers. Attach the new hose to the caliper using new sealing washers and tighten the banjo fitting bolt. Install the hose, ensuring it isn't twisted, and check for contact with suspension or steering components. Bleed the brake system and test the brakes before normal operation. When replacing brake lines, use the correct steel parts and avoid using copper tubing. Prefabricated brake lines with flared tube ends and fittings can be bent to the proper shapes using a tubing bender. Ensure the new line is well supported and has clearance from moving or hot components. After installation, check the master cylinder fluid level, add fluid if necessary, bleed the brake system, and test the brakes before normal operation.
