To inspect and replace flexible hoses, start by raising the vehicle and securely supporting it on jackstands. Thoroughly check the hoses for cracks, chafing, leaks, blisters, and other damage. Use a light and mirror to see into restricted areas. If any hose exhibits these conditions, replace it with a new one. To disconnect the brake line from the hose fitting, use an open-end wrench on the hose fitting and a flare-nut wrench on the line fitting, being careful not to bend the frame bracket or brake line. Remove the U-clip from the female fitting at the bracket using pliers, then remove the hose from the bracket. At the caliper end of the hose, remove the bolt from the fitting block and take off the hose and copper gaskets on either side of the fitting block. When installing the hose, always use new copper gaskets and lubricate all bolt threads with clean brake fluid. Attach the hose to the caliper with the fitting flange engaged with the caliper locating ledge. Install the female fitting in the hose bracket without twisting the hose. Use the U-clip to retain the female fitting to the frame bracket. Attach the brake line to the hose fitting and tighten the fitting using two wrenches. Ensure there are no kinks in the hose and that it doesn't contact any part of the suspension. Check this by turning the wheels to extreme left and right positions. After installation, check the master cylinder fluid level, add fluid if necessary, bleed the brake system, and test the brakes before driving in traffic. When replacing metal brake lines, ensure you purchase the correct replacement parts and avoid using copper or any other tubing. Prefabricated brake lines of various lengths can be bent with a tubing bender. When installing the new line, make sure it is securely supported in the brackets with sufficient clearance from moving or hot components. After installation, check the master cylinder fluid level, add fluid if necessary, bleed the brake system, and test the brakes before driving in traffic.
