The Ford Excursion was manufactured between the years of 2000 and 2005 by the Ford Motor Company. The large SUV featured front disc brakes on both two wheel drive and four wheel drive models. Some Excursions in the two wheel and four wheel drive categories also featured rear disc brakes. The main component of disc brakes is the rotor, also referred to as the disc. The hydraulic pistons of the calipers extend outward on braking demand, squeezing the brake pad friction material against the surface of the rotor, thus slowing and stopping the vehicle.

Remove the brake rotor from the hub. If the brake rotor does not come off the hub due to rust and other corrosives, spray the penetrating lubricant around the center hub hole of the rotor and allow a few minutes for the spray to soak in. Use a hammer to strike the inner plate of the rotor outward and turn the rotor 1/4 turn between strikes until the rotor breaks free from the hub. On rear rotors, strike the front hub of the rotor (being careful not to hit the lug studs) and turn 1/4 turn between strikes until the rotor breaks free from the hub.
