Nissan 46210-1AA2A Rear Brake Hose Assembly

About every six months, with the vehicle raised and securely supported 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 components of the brake system. Use a light and mirror for a thorough check, and replace any damaged hose with a new one. To replace brake hoses, loosen the wheel lug nuts, raise the vehicle, and remove the wheel. Unscrew the brake line fitting from the hose at the bracket using a flare-nut wrench to avoid rounding off the corners. Remove the U-clip from the female fitting at the bracket with pliers and pass the hose through the bracket. At the caliper end, remove the banjo bolt and separate the hose from the caliper, ensuring to replace the two sealing washers during installation. For front brake hoses, also remove the U-clip from the strut bracket before detaching the hose. To install the new hose, pass the caliper fitting end through the strut bracket, connect it to the caliper with the banjo bolt and new sealing washers, and ensure the hose is not twisted. Route the hose into the frame bracket, connect the brake line fitting by hand, install the U-clip, and tighten the fitting securely. After installation, check the master cylinder fluid level and add fluid as necessary, then bleed the brake system and test the brakes carefully before driving. When replacing metal brake lines, use the correct steel parts and avoid copper tubing. Prefabricated brake lines with flared tube ends and installed fittings are available at auto parts stores. Ensure the new line is securely supported in the brackets and has adequate clearance from moving or hot components.
