About every six months, with the vehicle raised and securely placed on jackstands, inspect the flexible hoses connecting the steel brake lines to the front and rear brake assemblies for cracks, chafing, leaks, blisters, and other damage, as these are crucial parts of the brake system requiring thorough examination with a light and mirror. If any defects are found, replace the hose with a new one. Begin by cleaning all dirt from the ends of the hose, then use a flare-nut wrench to unscrew the tube nut to avoid rounding off the corners, followed by removing the bolt(s) or clip(s) securing the hose to the body and suspension components. For front brake hoses, unscrew the brake line fitting while holding the fitting block with another wrench, remove the mounting bolts, and detach the hose from the caliper by unscrewing the banjo bolt. For rear brake hoses, hold the bracket with pliers, remove the clip, and unscrew the banjo bolt to detach the hose from the caliper. Disconnect the hose from the caliper, discarding the sealing washers, and then attach the new brake hose using new sealing washers, tightening the banjo fitting bolt to the specified torque. Reverse the removal procedure to install the hose, ensuring it isn't twisted, and check that suspension or steering components do not contact the hose by having an assistant push down on the vehicle and turn the steering wheel lock-to-lock during inspection. When replacing brake lines, use the correct parts, avoiding copper tubing, and purchase steel brake lines from a dealer or auto parts store. Prefabricated brake lines with pre-flared tube ends and installed fittings are available and can be bent to the proper shapes using a tubing bender. Ensure the new line is well supported in the brackets and has sufficient clearance from moving or hot components. After installation, check the master cylinder fluid level, add fluid as necessary, and bleed the brake system, testing the brakes carefully before returning the vehicle to normal operation.
