You can Select Your Vehicle to check if 90947-A2003 fits your vehicle.

To ensure the proper functioning of your brake system, it is recommended to inspect the flexible hoses connecting the steel brake lines with the front and rear brake assemblies every six months. With the vehicle raised securely on jack stands, carefully examine the hoses for cracks, chafing, leaks, blisters, or any other damage using light and mirrors. If any of these defects are detected, replace the hose with a new one. For replacing the flexible hoses, start by cleaning the dirt from the hose ends. Disconnect the brake line from the hose fitting, taking care not to bend the frame bracket or line. If necessary, use penetrating oil to loosen the connections. Remove the U-clip from the female fitting at the bracket and detach the hose from the bracket. If the hose is directly connected to the caliper, disconnect the hose fitting from the caliper by removing the banjo bolt. Replace the copper washers with new ones and attach the new brake hose to the caliper. Also, detach the hose from the front shock absorber bracket. Pass the female fitting through the frame or frame bracket with the least amount of twist in the hose and install the fitting in this position. 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 and tighten the tube nut securely. Check that the suspension or steering components do not make contact with the hose by having an assistant push down on the vehicle and turn the steering wheel lock-to-lock during the inspection. Finally, bleed the brake lines to ensure proper operation. When replacing brake lines, always use the appropriate steel brake lines instead of copper tubing. Prefabricated brake lines with flared ends and fittings already installed can be purchased. If necessary, carefully bend the line to the correct shape using a tube bender. During installation, ensure that the new line is well supported in the brackets and has sufficient clearance from moving or hot components. After installation, check the brake fluid reservoir level and add fluid if needed. Bleed the brake system and thoroughly test the brakes before returning the vehicle to normal operation. By following these steps, you can effectively inspect and replace flexible hoses and metal brake lines in your brake system.
