    Q:
    How do you properly attach the hose to the bracket for the Brake Line on the 2008 Cadillac DTS? Posted by Antin S.
    A:
    Install the female fitting in the hose bracket without twisting the hose. Use the U-clip to retain the female fitting to the frame bracket. Ensure there are no kinks in the hose and that it doesn't contact any part of the suspension. Check this by turning the wheels to extreme left and right positions.
