One of the tools in the boot lid is apparently for emergency release of the EPB. Be careful with the widow maker jack. Disconnect the electrical connection before hand and get the AA to secure the cable as not to damage it when you're back driving. I think you remove the two bolts to free the motor off the caliper with this tool and then wind back the piston. The two bolts and the drive spindle share the same hex pattern so only one tool.
