About every six months, with the vehicle raised and securely placed on jackstands, inspect the flexible hoses connecting the steel brake lines to the front and rear brake assemblies for cracks, chafing, leaks, blisters, and other damage, as these are crucial parts of the brake system. A thorough check requires a light and mirror, and any defective hose should be replaced with a new one. Begin by cleaning dirt from the hose ends, then detach the brake hose from any brackets or mounting points between the brake line and hose junction and the caliper, using a flare-nut wrench to unscrew the brake line threaded fitting and pliers to remove the U-clip. To disconnect the brake hose from the brake line, unscrew the metal tube nut with a flare nut wrench, remove the U-clip from the female fitting at the bracket, and take off the hose. Disconnect the hose from the caliper, discarding the sealing washers on either side of the fitting, and for S-type models, loosen the tube nut fitting at the caliper. Attach the new brake hose to the caliper using new sealing washers and tighten the banjo bolt to the specified torque. Reattach the brake hose to the metal line by inserting the end through the frame bracket, ensuring it isn't twisted, and securely tightening the tube nut fitting while installing the U-clip at the frame bracket. Check that suspension or steering components do not contact the hose, having an assistant push down on the vehicle and turn the steering wheel lock-to-lock during inspection. When replacing brake lines, use the correct parts, avoiding copper tubing, and purchase steel brake lines from a dealer or auto parts store. Prefabricated brake lines with flared tube ends and installed fittings are available and can be bent to the proper shapes using a tubing bender. Ensure the new line is well supported in the brackets and has ample clearance from moving or hot components. After installation, check the master cylinder fluid level, add fluid as necessary, and bleed the brake system, testing the brakes carefully before returning the vehicle to normal operation.
