Before you begin the caliper overhaul, make sure there is a rebuild kit and then work in pairs as always. Take off the caliper guide pin(s) and caliper. Clean up the caliper, take out the piston, dust boot and piston seal. Dispose of all rubber parts and clean the rest of the components. Check for damage and replace any parts if need be. Put back lubricant and reassemble caliper; put in new bushings; fit the bleeder screw again. Clean and grease caliper guide pin(s) and mounting bracket. Mount brake pads on caliper, reconnect brake hose, bleed brakes; check air pressure now. Fit wheels again, lower vehicle then tighten nuts again on wheel studs to specification.

Start by loosening the wheel lug nuts, raising the front of the vehicle, and securely supporting it on jackstands. Remove the front wheels. If the caliper removal is solely for accessing other components, you don't need to remove the brake hose. However, for an overhaul, remove the brake hose inlet fitting bolt and detach the hose, taking precautions to prevent fluid spillage and contamination.
