Always replace the calipers in pairs; never replace just one. To remove, first loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the wheels. Next, disconnect the brake hose by removing the banjo bolt and plugging the hose to prevent contaminants from entering the brake system and to minimize brake fluid loss. If only accessing other components, support the caliper with wire instead of detaching the hose. Then, remove the caliper mounting bolts and take off the caliper, detaching the caliper bracket from the steering or rear knuckle if necessary. For installation, reverse the removal steps, ensuring to tighten the caliper mounting bolts (and bracket bolts, if removed) to the specified torque. Install new sealing washers on both sides of the brake hose banjo fitting and tighten the banjo bolt to the specified torque. Finally, bleed the brake system, install the wheels and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque.
