Q: How should I inspect and replace flexible brake hoses and brake line for Buick Enclave,Chevrolet Traverse,GMC Acadia and Saturn Outlook?
A: 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 remove a brake hose, clean all dirt away from the ends of the hose and unscrew the tube nut with a flare-nut wrench. Remove the bolts or clips securing the hose to the body and disconnect the hose from the caliper, discarding the sealing washers. Attach the new brake hose to the caliper using new sealing washers and tighten the banjo fitting bolt to the proper torque specifications. Make sure the hose isn't twisted during installation and check for any contact with suspension or steering components. Bleed the brake system after installation. When replacing metal brake lines, use the correct parts and avoid using copper tubing. Prefabricated brake lines with flared tube ends and fittings installed 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 enough 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 carefully before normal operation.
