If you have noticed track marks or prominent wear on your brake rotor, it may be to replace it. Squealing brakes or a soft response when you press on the brake pedal are other clues that replacement may be in order. Replacing the rotors on the rear brakes on a 1996 Ford Explorer is a task that the average owner can perform. It's relatively quick and just takes the right tools and a little elbow grease.
Put on a filtered face mask and safety glasses before you begin operating on your brakes, since brake pad dust may contain small amounts of asbestos.2
Jack up the rear end of your 1996 Ford Explorer, place it on jack stands, and remove the wheel. Inspect the rotor for track marks or prevalent wear to confirm it does indeed need replacing.3
Remove the rear brake caliper by loosening and removing the mounting bolts with a socket wrench. Lift the caliper gently from the caliper mount, paying extra attention to avoid damage to the brake fluid line.4
Remove the brake pads and hardware. Loosen and remove the rear brake caliper mounting bolts with a socket wrench or another appropriate tool. Remove the caliper mount gently from the vehicle.5
Remove the retaining screw from the disc mounting hole and tap the rotor with a rubber mallet to release any rust buildup between it and the bearing hub. Lift the rotor away from the vehicle with both hands, being careful not to drop it. If the rotor is extremely rusted, turn and pull simultaneously while applying more force.6
Clean the mating surface on the wheel hub and place the new rotor into position. Reconstruct the brake system in the reverse order. Put the wheel back on and check the rotor on the opposite side (often brake systems wear quite evenly).
