1. Check vehicle service information for any special ­procedures for piston retraction, electronic brake assist system deactivation or ­proportioning/metering valve reset.  

2. Upon receiving the new caliper, make sure the replacement caliper matches old caliper. This includes making sure the correct left and right calipers were included in the order. 
3. Always install caliper with bleeder(s) toward the highest point of the caliper. 
4. Inspect brake hoses and lines for wear, degradation or damage, and repair or replace as necessary. If the brake system has undergone extreme thermal stress, it is a good idea to replace the hose.  
5. Flush old brake fluid from system before installing replacement caliper. 
6. Use only the vehicle manufacturer’s recommended brake fluid. 
7. Follow vehicle manufacturer’s recommended bleeding ­procedure. Often a scan tool is required to fully bleed the system.
8. Follow vehicle manufacturer’s torque specifications for all caliper bracket bolts and guide pins. Some fasteners are torque to yield and may need replacement.  
9. Road test vehicle after service to check for proper operation. Check for brake fluid leaks after road test.
