About every six months, it is important to inspect the flexible hoses that connect the steel brake lines with the front and rear brake assemblies for any cracks, chafing, leaks, blisters, or other damage. This inspection should be done with the vehicle raised and securely placed on jackstands, using a light and mirror for a thorough check. If any of the above defects are found, the hose should be replaced with a new one. To remove a brake hose, clean away any dirt from the ends and unscrew the tube nut with a flare-nut wrench. Then remove the bolt(s) or clip(s) securing the hose to the body. Disconnect the hose from the caliper, discarding the sealing washers, and attach the new hose using new sealing washers. Make sure the hose isn't twisted and check for any contact with suspension or steering components. Bleed the brake system after installation. When replacing brake lines, use the correct 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 in the brackets and has enough 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 carefully before normal operation of the vehicle.
