Ford 6L5Z-2267-A Brake Tube Assembly

If the vehicle is equipped with a four-wheel Anti-lock Brake System (ABS), plug the brake line immediately after disconnecting it from the brake hose to prevent fluid from draining and air from entering the Hydraulic Control Unit (HCU), as bleeding the HCU requires an expensive tool. Inspect the rubber hoses connecting the steel brake lines to the front and rear brake assemblies every six months while the vehicle is securely raised on jackstands, checking for cracks, chafing, leaks, and blisters; replace any damaged hoses. To replace a flexible hose, use a flare nut wrench to disconnect the brake line from the hose fitting without bending the frame bracket or brake line, holding the fitting with a wrench to prevent twisting. Remove the large retaining clip to detach the hose from the bracket and body, and plug the metal brake line immediately to avoid air entering the HCU. Remove the banjo bolt from the caliper, discard the sealing washers, and connect the new hose to the caliper with new sealing washers, tightening the banjo bolt to the specified torque. Connect the other end of the line to the bracket on the chassis without twisting the hose, then connect the metal brake line to the hose fitting by hand and tighten securely with a flare nut wrench, ensuring no kinks in the hose and that it does not contact any suspension parts. When replacing brake lines, use the correct steel parts and avoid copper tubing; prefabricated brake lines with flared ends and fittings are available at auto parts stores. Ensure the new line is securely supported and has clearance from moving or hot components, check the master cylinder fluid level after installation, and bleed the brake system before carefully testing the brakes in traffic.

A hydraulic system leak is indicated, which could be at the master cylinder, wheel cylinder, caliper, hose, or line. Hydraulic leaks must be repaired immediately.
