Toyota 90947-02784 Hose, Flexible

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 these defects, they should be replaced with new ones. To replace the flexible hoses, start by cleaning any dirt away from the ends of the hose. Then, disconnect the brake line from the hose fitting, being careful not to bend the frame bracket or line. Remove the U-clip from the female fitting at the bracket and remove the hose from the bracket. Disconnect the hose from the Brake Caliper, discarding the copper washers on either side of the fitting. Attach the new brake hose to the caliper using new copper washers. Pass the female fitting through the frame or frame bracket, ensuring the least amount of twist in the hose. Install the U-clip in the female fitting at the frame bracket. Attach the brake line to the hose fitting using a back-up wrench and tighten the tube nut securely. Check to make sure the suspension or steering components do not make contact with the hose. Bleed the brake system. When replacing metal brake lines, use the correct parts and avoid using copper tubing. Prefabricated brake lines with flared ends and fittings installed are available and can be carefully bent to the proper shape if needed. Ensure the new line is well supported in the brackets and has enough clearance between moving or hot components. After installation, check the Brake Master Cylinder fluid level, add fluid if necessary, bleed the brake system, and test the brakes before normal operation of the vehicle.
