Vmaximus,I don't know if it varies for different years but my manual is for FJS6001,on 15-2 it says ... Rear brake disc bolt 42N.m (4.3kgf.m,31lbf.ft) ALOC bolt:replace with new one,it comes under wheels rather than brakes

Probably the same for yours,but just check the service information page ..Rear Wheel/Suspension section to be sure
