Take off the front wheel's lug nuts while keeping them loose, raise your vehicle up from the front with jackstands, and safely support it before taking the front wheels off. Plug the
Brake Line at its connection to the caliper, using seals to block foreign material. Only do this if you must disconnect for access to other brake parts. Undo the caliper bolts, and pull the caliper away from its holder. Run the brake line back in place, fitting fresh sealing washers one per side, and tighten up the bolt that holds the caliper and the banjo bolt. Before wheel installation, release excess brake fluid from the system. Secure the wheels by hand-tightening their lug nuts, then lower the vehicle while tightening all lug nuts securely. Fasten but do not take off the lug nuts from the rear wheels, lift the back of the car, and put jackstands under it securely before you remove the rear wheels. Take off the banjo bolt and disconnect the brake line from the caliper, using a plugging fitting to stop fluid from spilling out and getting contaminated unless you need to remove the caliper for other parts. Turn off the hydraulic caliper mounting bolts while pinching the caliper pins with another wrench, allowing you to slide the caliper loose from its attachment bracket. Reinstall by plugging the brake line opening, putting new sealing washers on both sides, tightening caliper fasteners, and screwing the banjo bolt in place. Bleed the brake system, then install the wheels and lug nuts, lower the vehicle, and tighten the lug nuts.
