    Q:
    What are the initial steps to replace the flexible Brake Line hoses in the brake system for the 2007 Chevrolet Avalanche? Posted by Shadow W.
    A:
    The initial steps to replace flexible hoses in the brake system are as follows: Clean the ends of the hose. 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. Remove any mounting fasteners for brackets that secure the hose to other components. On models where the hose is connected directly to the caliper, disconnect the hose fitting from the caliper by removing the banjo bolt. Discard the copper washers on both sides of the fitting and use new copper washers to attach the new brake hose to the caliper.

    To install the new brake hose, follow these steps: Route the hose exactly as the original one was. Mount any hose brackets that secure the hose to other components, as equipped. Pass the female fitting through the frame or frame bracket and install it in position with the least amount of twist in the hose. Install the U-clip in the female fitting at the frame bracket.
