The initial steps to replace flexible hoses in the brake system are as follows: Clean the ends of the hose. Disconnect the brake line from the hose fitting, being careful not to bend the frame bracket or line. Remove the U-clip from the female fitting at the bracket and remove the hose from the bracket. Remove any mounting fasteners for brackets that secure the hose to other components. On models where the hose is connected directly to the caliper, disconnect the hose fitting from the caliper by removing the banjo bolt. Discard the copper washers on both sides of the fitting and use new copper washers to attach the new brake hose to the caliper.

To install the new brake hose, follow these steps: Route the hose exactly as the original one was. Mount any hose brackets that secure the hose to other components, as equipped. Pass the female fitting through the frame or frame bracket and install it in position with the least amount of twist in the hose. Install the U-clip in the female fitting at the frame bracket. Attach the brake line to the hose fitting using a backup wrench on the fitting. Tighten the tube nut securely.

To complete the brake hose replacement, follow these steps: Ensure that the replacement hose follows the same path as the original one to avoid contact with moving suspension or steering components. Bleed the brake lines to remove any air and ensure proper brake system operation. When replacing metal brake lines, use the correct parts and do not use copper tubing for any brake system components. Use prefabricated brake lines with the ends already flared and fittings installed. Carefully bend the new line to the proper shape if necessary, using a tube bender. Support the new line well in the brackets and ensure there is plenty of clearance between moving or hot components. After installation, check the brake fluid reservoir level and add fluid as necessary. Bleed the brake system to ensure all air is removed. Confirm that the brakes are fully operational before resuming normal driving.
