you will need a 7mm hex socket, for the main shoe, and if you intend to remove the disc/replace it.. you will need a 10mm hex socket.. get some thread lock for the 10mm's so when you tighten them back up they dont shake themselves loose.. and torque wrench them to 95Nm :) the 7mm will need to be done to 30Nm
good luck.. and careful when you get the shoes off.. dont hang them by the hoses.
