How do you change back driverside brake line on a 1997 mountaineer?

To change the driver's side brake line on a 1997 Mercury Mountaineer, start by safely lifting the vehicle and removing the wheel for access. Then, locate the brake line, disconnect it from the brake caliper and the hard line using a line wrench to prevent damage to the fittings. Replace the old line with a new one, ensuring all connections are tight and secure. Finally, bleed the brake system to remove any air and ensure proper brake function before reassembling the wheel and lowering the vehicle.
