Every six months, it is important to inspect the rubber hoses that connect the steel brake lines with the front and rear brake assemblies for any cracks, chafing, leaks, blisters, or other damage. This inspection should be thorough, using a light and mirror if necessary. If any of these conditions are found, the hose should be replaced with a new one. To replace the front flexible brake hoses, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and unscrew the brake line fitting from the hose at the bracket. Use a flare-nut wrench to prevent rounding off the corners of the fitting nut. Remove the clip from the bracket and detach the hose. At the caliper end of the hose, remove the inlet fitting bolt and separate the hose from the caliper. Replace the copper sealing washers with new ones. To install the hose, connect the fitting to the caliper with the inlet fitting bolt and new sealing washers. Route the hose into its original location, ensuring it isn't twisted, and tighten the hose bracket bolt securely. Connect the brake line fitting and tighten it securely. Bleed the caliper, install the wheel, lower the vehicle, and tighten the lug nuts. For the rear flexible brake hose replacement, raise the rear of the vehicle on jackstands and block the front wheels. Unscrew the brake line fitting from the hose at the chassis end using a flare-nut wrench. Remove the clip from the bracket and detach the hose. At the brake fitting junction block on top of the left side of the rear axle housing, remove the hose from the junction block. To install the hose, connect the fitting to the junction block with a new sealing washer. Route the hose into its original location, ensuring it isn't twisted, and secure it with its clip. Connect the brake line fitting and tighten it securely. Bleed the rear brakes, install the wheel, lower the vehicle, and tighten the lug nuts. When replacing metal brake lines, use the correct parts and avoid using copper tubing. Prefabricated brake lines are available and must be bent to the proper shapes using a tubing bender. Ensure the new line is securely supported in the brackets and has enough clearance between moving or hot components. Check the master cylinder fluid level, add fluid if necessary, bleed the brake system, and test the brakes before driving the vehicle in traffic.

About every six months, it is important to inspect the flexible hoses that connect the steel brake lines with the front and rear brake assemblies for any cracks, chafing, leaks, blisters, or other damage. This inspection should be done with the vehicle raised and securely placed on jackstands, using a light and mirror for a thorough check. If any of the hoses exhibit any of the mentioned defects, they should be replaced with new ones. To disconnect a brake hose from the brake line, the metal tube nut should be unscrewed with a flare nut wrench, and the U-clip should be removed from the female fitting at the bracket. The hose can then be removed from the bracket. When disconnecting the hose from the caliper, the sealing washers on either side of the fitting should be discarded, and new sealing washers should be used when attaching the new brake hose to the caliper. To reattach a brake hose to the metal line, the end of the hose should be inserted through the frame bracket, ensuring that the hose isn't twisted, and the metal line should be attached by tightening the tube nut fitting securely. The clip should be installed at the frame bracket. It is important to check that the suspension or steering components do not make contact with the hose, and this can be done by having an assistant push down on the vehicle and turn the steering wheel lock-to-lock during inspection. Finally, the brake system should be bled after completing the hose replacement. When replacing brake lines, it is crucial to use the correct parts and avoid using copper tubing. Steel brake lines can be purchased, and prefabricated brake lines with flared tube ends and fittings already installed are available at auto parts stores and dealer parts departments. These lines can be bent to the proper shapes using a tubing bender. During installation, it is important to ensure that the new line is well supported in the brackets and has sufficient clearance between moving or hot components. After installation, the master cylinder fluid level should be checked and fluid should be added as necessary. The brake system should be bled and the brakes should be carefully tested before the vehicle is placed into normal operation.

When replacing flexible hoses, it is important to clean the ends of the hose and disconnect the brake line from the hose fitting, being careful not to bend the frame bracket or line. The U-clip should be removed from the female fitting at the bracket and the hose should be removed from the bracket. Any mounting fasteners for brackets that secure the hose to other components should be removed, and on models where the hose is connected directly to the caliper, the hose fitting should be disconnected from the caliper by removing the banjo bolt. The copper washers on both sides of the fitting should be discarded and new copper washers should be used to attach the new brake hose to the caliper. The hose should be routed exactly as the original one was and any hose brackets that secure the hose to other components should be mounted, as equipped. The female fitting should be passed through the frame or frame bracket and installed in position with the least amount of twist in the hose. The U-clip should be installed in the female fitting at the frame bracket and the brake line should be attached to the hose fitting using a backup wrench on the fitting. The tube nut should be tightened securely and the replacement hose should follow the same path as the original one to avoid contact with moving suspension or steering components. Finally, the brake lines should be bled. When replacing metal brake lines, it is important to use the correct parts and not use copper tubing for any brake system components. Prefabricated brake lines, with the ends already flared and fittings installed, should be used and carefully bent to the proper shape if necessary using a tube bender. The new line should be well supported in the brackets and have plenty of clearance between moving or hot components. After installation, the brake fluid reservoir level should be checked and fluid added as necessary. The brake system should be bled and the brakes should be confirmed to be fully operational before resuming normal driving.

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.

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.
