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 all dirt away from the ends and unscrew the tube nut with a flare-nut wrench. Remove the bolt(s) or clip(s) securing the hose to the body and disconnect it from the caliper, discarding the sealing washers. Attach the new brake hose to the caliper using new sealing washers and tighten the banjo fitting bolt to the specified torque. Make sure the hose isn't twisted during installation and check for any contact with suspension or steering components. Have an assistant push down on the vehicle and turn the steering wheel lock-to-lock during the inspection. Finally, bleed the brake system. When replacing brake lines, use steel brake lines and avoid using copper tubing. Prefabricated brake lines with flared tube ends and fittings are available and can be bent to the proper shapes using a tubing bender. Ensure that 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 and add fluid if necessary. Bleed the brake system.
