The proper way to install brakes on a 2002 Chevy Tahoe is to replace or machine the rotors every time the pads are replaced. The minimum thickness on the front rotors is 30.7 mm after measurement and the deduction of an additional 30 thousandths for machining. Used pads have grooves worn into them, which match the grooves in the rotor. Installing new pads on used rotors will cause the pads to wear rapidly to accommodate the grooves in the rotor.
Instructions

Loosen all the lugs nuts one complete turn, using the lug wrench. This will make them easier to remove once the tire is elevated. Raise the Tahoe with the floor jack and place jack stands under the frame. Lower the vehicle to rest on the stands. Continue removing the lug nuts and then the tires.
2Open the caliper bleeder screw one turn, using a socket. Insert the common screwdriver between the inside brake pad and the rotor. Pry the inside pad toward the engine, thereby forcing the caliper piston into its bore. Close the bleeder screw and tighten it snug only.
3Remove the two caliper-retaining bolts, using a socket. Lift the caliper off the rotor and suspend it from the coil spring with the use of a wire or rope. Pull the brake pads from the caliper-mounting bracket. Remove the two mounting bracket bolts, using a socket. Remove the bracket.
4Hit the center of the rotor with the hammer, close to the wheel studs, to break it loose from the hub. Pull the rotor off. Install the new or machined rotor. Install the mounting bracket and tighten the two rear bolts to 129 foot-pounds of torque.
5Spread anti-seize compound on the top and bottom anti-rattle springs in the mounting bracket. Install the brake pads in the mounting bracket by sliding them over the anti-rattle springs. Use your hand to squeeze the pads against the rotor.
6Lower the caliper over the brake pads on the mounting bracket. Spread some anti-seize compound on the retaining bolts and insert them into the caliper, then tighten them to 32 foot-pounds of torque.
7Install the wheel and lug nuts. Tighten the lug nuts just enough for them to be seated in the wheel. Lower the Tahoe and tighten the lug nuts to 120 foot-pounds of torque. Open the hood and remove the cap from the master cylinder reservoir. Fill the reservoir to the "Full" mark and replace the cap. Start the vehicle and pump the brakes 10 times before attempting to move it.
