When replacing the disc brake pads on a 2005 Ford F-150, it is common practice to either machine or replace the rotors. In order for 100 percent of the pads surface to contact the rotor to maximize performance, the surface of the rotor must be free of grooves. All rotors groove with use. The pad and rotor wear in as one, with the grooves in the pad having corresponding grooves in the rotor.

Loosen the lug nuts one complete turn counterclockwise using the lug wrench. Raise the front of the truck using the floor jack, and place the jack stands under the frame just to the rear of the front tires. Lower the truck so it rests on the stands. Continue removing the lug nuts and ultimately the wheels.
2Insert the screwdriver through the hole in the center of the caliper and pry the inner brake pad away from the rotor just enough to get the screwdriver between the rotor and pad. Remove the two caliper bolts using a socket.
3Lift the caliper off the mounting bracket and support it from the coil spring with a suitable piece of wire. Push the corner of the outside pad in and pull down to dislodge the spring clip on the outside of the caliper that pinches the pad to the caliper. Pull the inside pad straight out of the caliper piston bore.
4Lift the anti-rattle clips off the caliper-mounting bracket. Install the new anti-rattle clips on the mounting bracket. Install the new pads starting with the inside pad. The inside pad has two spring steel clips on the back. Push these clips in the cavity into the caliper piston to secure the pad. Push the outside pad up from the bottom of the caliper spreading the spring steel over the front of the caliper. In essence, the front spring clips squeeze the caliper holding the outside pad secure.
5Lower the caliper over the rotor and install the caliper mounting bolts. Torque them to 28 foot-pounds of torque. Install the wheel and tighten the lug nuts with the lug wrench. Lower the truck to the ground, and torque the wheel nuts to 120 foot-pounds of torque.
