       Important: Do not use ISO flares for the rear brake pipe connections to the rear wheel cylinders.

    • Refer to Master Cylinder Description for an illustration depicting the brake pipe layout and locations. Brake pipes that are to be locally fabricated, should only be ISO flared, and not double lap flared.
    • Rear brake front pipes (mid) should not be locally fabricated. These pipes should be ordered through your GM parts dealer.
