To inspect the rubber hoses connecting steel brake lines with front and rear brake assemblies, raise the vehicle securely on jackstands every six months. Check for cracks, chafing, leaks, blisters, or other damage using a light and mirror for thorough inspection. Replace any hose displaying these conditions with a new one to ensure brake system integrity. For replacing flexible hoses, loosen wheel lug nuts, raise and support the vehicle on jackstands, and remove the wheel. Unscrew the brake line fitting from the hose using a flare-nut wrench to protect the corners. Remove the U-clip from the bracket at the frame and pass the hose through. At the caliper end, remove the banjo fitting bolt and separate the hose from the caliper, replacing the copper washers. Remove the U-clip from the strut bracket, then feed the hose through. Install the hose by connecting the caliper fitting to the caliper using the banjo bolt and washers. Insert the metal support into the strut bracket, install the U-clip, and ensure the hose isn't twisted. Route the hose into the frame bracket, connect the brake line fitting, and secure it with a clip and E-ring if present. Bleed the caliper, install the wheel, lower the vehicle, and tighten the lug nuts. When replacing metal brake lines, use genuine steel brake lines purchased from a dealer or auto parts store. Prefabricated brake lines with flared tube ends and fittings are available. During installation, ensure proper support and clearance for the new line, avoiding contact with moving or hot components. After installation, check the master cylinder fluid level, add fluid as needed, bleed the brake system, and test the brakes before driving in traffic.
