You will need a T55 Torx bit to remove the front caliper of a 2001 Silverado 1500. A torx bit is a screw with a six point star shaped head. These come in different sizes.
Remove the two bolts and use a screwdriver against the hub and caliper.
First, raise and support the vehicle. Then remove the wheel and the tire assembly. Also remove the caliper from the steering knuckle, and then remove the caliper adapter assembly.
