About every six months, with the vehicle raised and supported securely on jackstands, inspect the rubber 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. Use a light and mirror for a thorough check, and replace any hose showing signs of wear. To replace a disc brake hose, loosen the wheel lug nuts, raise the vehicle, and remove the wheel. Unscrew the brake line fitting from the hose using a flare-nut wrench to avoid rounding off the corners, and hold the hose fitting with an open-end wrench if the bracket bends. Remove the U-clip from the female fitting at the bracket with pliers and pass the hose through the bracket. At the caliper end, remove the banjo fitting bolt and separate the hose, ensuring to replace the two copper sealing washers during installation. Unbolt the hose from the strut bracket if applicable, then install the new hose in reverse order, ensuring it isn't twisted, and securely tighten the banjo bolt and brake hose-to-brake line fitting. After installation, check the master cylinder fluid level, add fluid if necessary, and bleed the brake system before carefully testing the brakes. When replacing metal brake lines, use the correct steel parts and avoid copper tubing. Prefabricated brake lines with flared tube ends and installed fittings are available at auto parts stores and can be bent to the proper shape. Ensure the new line is securely supported in brackets and has adequate clearance from moving or hot components.
