Ford Motor Company introduced the Ford Aerostar in 1986. When the 1993 Aerostar hit the showroom, it was equipped with either a 3.0-liter V-6 engine or a 4.0-liter V-6 and a choice of two-wheel or four-wheel drive. The front brakes on the 1993 Aerostar are ventilated disc brakes; the rear brakes on both the two-wheel and four-wheel drive models are drum brakes. All of the tools necessary for this project can be found at an auto parts store.
Tools Used: Tools, Tire iron, 2-ton or greater capacity floor jack, 2 jack stands, Flat-head screwdriver, 1 can aerosol brake cleaner spray
Adjust the Rear Brakes
Remove the torque from the rear wheel lug nuts on the Aerostar, using a tire iron to turn the lug nuts counterclockwise. Raise the rear of the Aerostar using a 2-ton jack or a jack with greater capacity. Place jack stands beneath both ends of the rear axle housing, just inside the rear wheels. Remove the lug nuts completely from both rear wheels with a tire iron, then remove the rear wheels by hand.
Remove the brake drum from one side of the Aerostar by hand. Spray 1/2-can of aerosol brake parts cleaner onto the entire set of internal brake components, including the brake shoes and springs. Make sure you also spray the bottom side of the brake components, where you will be working. Visually inspect the rear brake shoes. You should have at least 3/16-inch brake shoe material on the shoes. If you do not have the right amount of shoe material or you notice the shoes are wearing unevenly, replace the brake shoes.
