How do you change front brake pads on a 2005 GMC Savana 3500?

To change the front brake pads on a 2005 GMC Savana 3500, start by loosening the lug nuts on the front wheels and lifting the vehicle with a jack. Remove the wheel and then locate the brake caliper; unbolt it and slide it off the rotor. Compress the caliper piston using a C-clamp, then remove the old pads and replace them with new ones. Reattach the caliper, secure it, and reassemble the wheel, making sure to torque the lug nuts properly before lowering the vehicle.
