How to replace the rear brake line on Buick LaCrosse?

Before starting work raise your vehicle and place supports under it. After removing the tire from the rear wheel you can begin replacing the brake hose. Put a rubber cover on the brake pipe fitting and cleanse it after removing any dust that collects on both components. Hold the hose fitting with an additional wrench to remove the brake pipe connection from the brake hose without harming the brake pipe components. Take out the brake hose from the bracket by removing its retaining clip from the mounting bracket. Take off the brake hose to caliper bolt from the brake caliper before detaching the brake hose from the brake caliper. Then remove both the brake hose and discard its attached copper brake hose gaskets. Place the brake hose into the vehicle before adding new copper gaskets and bolt the brake hose to its position. Grasp the brake caliper during installation of the brake hose to caliper bolt and tighten it to 54 nm (40 ft. Lbs.). Mount the brake hose on the bracket under vehicle weight while keeping bends out of the line to match the bracket notch. Put the retainer in place on the hose fitting at the bracket. Then disconnect the rubber cap or plug from end of brake pipe fitting and join it with brake hose by supporting with a back up wrench before tightening to 18 nm (13 ft. Lbs). Put back the rear tire and wheel parts while keeping the hose away from suspension components; adjust if the hose touches any parts. The last step is to drain the hydraulic brake lines and lower the vehicle.
